Re: [Scilab-users] Using Scilab on Linux Mint

On a laptop computer of mine with Intel (8:th gen.) integrated graphics, the

LIBGL_ALWAYS_SOFTWARE=1
makes them correct.

Re: [Scilab-users] Using Scilab on Linux Mint

[Stefan Du Rietz]

The strange thing is that at the moment, after

$ sudo apt update && sudo apt upgrade

the plotting works without setting a new environment variable! However, when I 
start Scilab from the command line, lots of Java errors are still reported.

Re: [Scilab-users] Using Scilab on Linux Mint

[Stefan Du Rietz]

Frederico,

First: How did you install Scilab in Linux Mint 21.2?
Version 6.1.1 with Software Manager or from the terminal (both from the 
repositories) or version 2023.1.0 from the Scilab download page?
I can then send a working desktop file to you.

Second: It is all about graphic drivers. I found this:
https://askubuntu.com/questions/1333764/scilab-graphic-window-appear-but-it-is-blank-there-is-no-plot-ubuntu-20-04-lts

Your questions:

1, 2) It can be either a global file in /usr/share/applications or a user-specific 
file in /home//.local/share/applications
Both will be visible in the Start menu.

3) Yes.

4) By searching the Internet (see above).

5) I hand over this one to the Scilab team or Samuel G!

Stefan

Stefan,

Thank you very much for your valuable help. However, it is embarrassing for me 
to confess that I'm quite new to Linux so I need a little more help:

1) Is the desktop file a system (global) file or an application file?
2) Where can I find it?
3) I assume once located I can edit it with any text editor, am I right?
4) Optional :)   How does one discover workarounds like this?
5) Is this a bug to be reported or it is a normal situation to have to tweak 
the desktop file? So far I haven't had this kind of problem with other programs 
using graphic capabilities.

Thank you again.

Hello all,

Very basic query but how do you print all the values from a result via 
mprintf?


e.g.

fac = factor(1729)
7 13 19

mprintf('Factors of 1729 are: %d\n', fac)
just prints 'Factors of 1729 are: 7

You may also use a Fortran syntax -- that supports automatic inline 
iterations, unlike C syntaxes -- instead of a  C one:


--> fac = factor(1729);
--> write(%io(2), fac, "(''Factors of 1729 are:'', 10(i2,2x))")

Factors of 1729 are: 7  13  19

Samuel

PS : i no longer receive messages from users@ since 2022-10-05 (last 
received).
So for the time being, i answer to old threads, to not break recent ones 
to which i can't reply, just read archives.




Too print all elements, the argument must be a column vector: fac'
And to avoid repeating the first wording, you can print it separately:

--> mprintf("Factors of 1729 are: "), mprintf("%d  ", fac')
Factors of 1729 are: 7  13  19

Re: [Scilab-users] Long delay before callback

[Stefan Du Rietz]

Stéphane, thank you very much for your example!

However, everyone of my callback functions is short-lived: it just does 
a few things and exits. Sometimes the response is instantaneous but 
sometimes it takes a long time. I have not so far managed to notice any 
pattern in that.

Re: [Scilab-users] Long delay before callback

[Stefan Du Rietz]

Hello Stéphane,

a minimal example works OK all the time ...

So, there must be something in my rather complex GUI environment, with 
many private functions, that does not. But since I get no warning or 
error messages, I don't know how to proceed.


Can the delays be due to timeouts?

Regards
Stefan

Re: [Scilab-users] Basic query - mprintf

[Stefan Du Rietz]

Of course you don't need to make the string s.

You have to transpose fac to get a column vector for mprintf and then 
transpose the column string vector to get a row string vector:


--> fac = msprintf("%d\n", fac')'
 fac  =
  "7"  "13"  "19"

and then concatenate the string so that it works for a variable number 
of elements in fac:


--> mprintf("Factors of 1729 are:  %s", strcat(fac,"  "))

Dear all,

Consider

M = 16
w = [ones(1,M/4),zeros(1,M/4)]
w = [w(1:M/2), 0, conj(w($:-1:2))]
v = ifft(w)
isreal(v)

The first 3 lines defines a real spectrum of a real signal, then the 
real signal is recovered and finally it is checked whether it is real or 
not.


What puzzles me is that the result is T (true). However, the definition 
of the ifft() involves complex operations, so at some point the numbers 
must be converted to a complex representation such as


1. + 0.i

so I would expect that the result included 0i so the result of the test 
should be F. Where is this null imaginary component removed?


I don't say this is wrong, but it is perplexing if compared to much more 
simple operations such as


sqrt(%i^4)

which yields 1. + 0.i, a complex representation of real scalar 1.

Maybe the fftw package is so refined to detect whether the result is 
actually real and removes the useless 0.i components?

Federico Miyara

Re: [Scilab-users] Cannot start Scilab 6.1.1

[Stefan Du Rietz]

When I did that, this message did not appear at startup in the Scilab 
command window:


"at line56 of function xmlGetValues ( 
/usr/local/scilab/scilab-6.1.1/share/scilab/modules/xml/macros/xmlGetValues.sci 
line 69 )
at line22 of function help ( 
/usr/local/scilab/scilab-6.1.1/share/scilab/modules/helptools/macros/help.sci 
line 34 )


xmlGetValues: Invalid XPath request."

However, the messages in the terminal remained, seemingly (from the 
content) because of the nVidia graphics driver.


After changing to "X.Org X server -- Noveau display driver from 
xserver-xorg-video-nouveau (open source)" they did not appear.


So, *with the nVidia driver*, if I start Scilab from a .desktop-file 
with JAVA_OPTIONS..., then no error messages are visible and the 
graphics seem to work.


Is there any possible disadvantage?

Stefan

[Scilab-users] Cannot start Scilab 6.1.1

[Stefan Du Rietz]

Hello all,
I am trying to get Scilab 6.1.1 running in a new Computer (Xubuntu Linux 
20-04, nVidia T-600 with proprietary driver) from 
scilab-6.1.1.bin.linux-x86_64.tar.gz in the same way as in another 
computer with the same OS but with Java 8,


But when I try to start from the terminal:

stefan@LenovoTS:/usr/local/scilab/scilab-6.1.1$ ./bin/scilab &
[1] 261325
stefan@LenovoTS:/usr/local/scilab/scilab-6.1.1$ X Error of failed

  Current serial number in output stream:  111
scilab-bin: error while loading shared libraries: libtinfo.so.5: cannot 
open shared object file: No such file or directory


I have uninstalled Java 11 and installed Java 8 to no avail.

If I install Scilab from Ubuntu repositories with

  $ sudo apt install scilab

I get a working version 6.1.0 (including graphics!), except for 
Preferences in both command window and Scinotes! So I can't change font 
in either of them.


Can anybody help?

Hi Scilabers

Today I tried to replace xdel(winsid()) in one of my scripts with 
close(winsid()) because Scilab shows a warning in the console:


Warning: Feature xdel(...) is obsolete and will be permanently removed 
in Scilab 6.2


Warning: Please use close(...) instead.

I am negatively surprised that the close() command takes a long time 
to execute with 5-10 windows open (a few seconds per window). The 
xdel() command can do it in a split second.




The issue comes not from close() but from the change offindobj() that it 
calls , noticeably 
to perform findobj("figure_id",id) in 6.1.1.
It does not impact only  close() for 
this case, that was processed as a special accelerated case 
 
in the former findobj().


This downgradingwas reported 
 7 months before 
releasing 6.1.1, and knowingly ignored, while it is perfectly fixable by 
restoring the fast special case.





What is the motivation for replacing xdel with close?


Both do the same thing. Scilab does not need duplicates.

Regards
Samuel



scf(id) is much faster than findobj("figure_id",id)

--> winsid()
 ans  =
   0.   1.

--> tic, f = []; for k=winsid(), f = [findobj("figure_id",k); f]; end, toc
 ans  =
   0.281087

--> tic, f = []; for k=winsid(), f = [scf(k); f]; end, toc
 ans  =
   0.000237

So, this is how to do it:

--> for k=winsid(), delete(scf(k)); end

it might be needed to ask datatip for other curves as well when 
analysing experimental data for instance.


I tried to set first axe as the current axes, sca(gcf().children(3)),

Do you see any reason for this limitation? Enhancement suggestion ?

if you don't need automatic scaling, you could use drawaxis() to get the 
second and third y-axis and then scale the y-data of those lines to plot 
them in the first axes. In your figure:


function y = yblu(yin)
  y = -1 + log10(yin)/3
endfunction

function y = yred(yin)
  y = -1 + yin * 2/240
endfunction

Then plot x and the function value of y.

Regards
Stefan

Dear all,

I found a limitation in the datatip manager of any figure window, as 
illustrated in the screen capture below, from the “multiple scaled 
plots” example : the datatip manager can catch only the last axe that 
was plotted, in the example only the red curve. This is a pity since it 
might be needed to ask datatip for other curves as well when analysing 
experimental data for instance.


I tried to set first axe as the current axes, sca(gcf().children(3)), 
but I didn’t manage to get the datatips for the first black curve.


Do you see any reason for this limitation? Enhancement suggestion ?

Re: [Scilab-users] 6.1.1 startup error

[Stefan Du Rietz]

Hello and many thanks for your replies!

Samuel,
Unfortunately, deleting SCIHOME/configuration.xml did not help (I have a 
vague memory that it worked previously). I agree with all your later 
comments.


Stéphane,
my changed line

gets replaced by

so it did not help.

Clément,
Deleting all the configuration files helped, BUT THEN ALL MY OWN FOLDERS 
WERE DELETED (a regression?)! Therefore all the changes I had made in my 
functions were lost!

Hi Stéphane, hi Samuel, hi all,

The idea behind SCIHOME is to have a version specific directory to avoid 
any issues when upgrading from Scilab versions to Scilab versions ; IMHO 
implementing an upgrade for files stored into this directory is for me a 
non-sense ; the upgrade could be done manually (as Samuel described) for 
the few users that copy the files between SCIHOMEs.

Hi,

The version of Scilab which generated the configuration.xml should be 
contained in some attribute of the top level element, i.e.


     

This would allow to trigger a proper upgrade of the file when the Scilab 
version differs or a regeneration if the file cannot be upgraded.

Hello Stefan,


This kind of error might arise when the content of the SCIHOME
directory of a previous scilab version is copied into the SCIHOME of
the current 6.1.1 version, for instance to avoid respecifying all
users preferences.
Unfortunately, when the template of some configuration file is
changed from one version to the next one, the file must be regenerated.

The issue should be fixed either by deleting the
SCIHOME/configuration.xml file, and regenerating it automatically
from scratch (quit Scilab and rerun it),
or by editing it and changing or adding the line just before the

Hello Samuel,

The size of ns (number of steps) and seq (sequence of values) are

For this reason, seq must be a list, leading to

 seq  =  p
 while  %T
 if  pmodulo(p, 2)
 p  =  p*3+1
 else
 p  =  p/2

prime = primes(20); [ns, seq] = ([],list()); for  i  =  1:length(prime)
 [ns(i),  seq(i)]  =  collatz(prime(i));
end --> ns' ans = 2. 8. 6. 17. 15. 10. 13. 21. --> seq seq = (1) = [2,1]

Of course, Samuel, I didn't realize that the length of seq was not

Re: [Scilab-users] Loop query

[Stefan Du Rietz]

One solution:

// Run the last (largest):
[ns, seq] = collatz(prime($))

// insert in new zeros vector:
ns = [zeros(prime-1), ns]
// insert seq in new zeros matrix:
seq = [zeros(length(seq), length(ns)-1), seq];

for  i = 1:length(prime)-1
  // Run collatz to get the new ns:
  [nsi, seqi] = collatz(prime(i));
  // insert in vector ns and matrix seq:
  ns(i) = nsi;
  seq(1:nsi, i) = seqi;
end

dispalay ns above seq:
[ns; seq]

I will try to analyze the issue deeper according to your 
propositions, and if I manage to isolate it, I will provide an example.

Maybe trying different os/java jdk might give some hint at the 
source for this bug...

I have now done that with a small, simple (Atom processor) computer with 
32-bit Windows 10 (updated) and there is no extra delay compared to 
Scilab 5.5.2 on the same computer (everything is pretty slow with Java 
GUI's compared to previous Scilab versions with Tcl/Tk!).


Stefan


And the same Java version in Window as in Linux aboves:
C:\Program Files\scilab-6.1.0\java\JRE\release
"1.8.0.151"

OK, that's a thing you can try: can you test 6.1.0 & 6.0.2 on the same 
computer, with everything else being identical but for the version of 
scilab?


Antoine

That is exactly what I have done! On a computer with 64-bit Xubuntu 
(Ubuntu with XFCE) 18.04 LTS with everything updated.


These files are exactly alike:
/usr/local/scilab/scilab-6.0.2/thirdparty/java/release

With which OS? I am only using Linux (Ubuntu).

As a workaround, in Linux, you can quickly get the number of lines:

I will add to the bug report.

That does not work if the file contains empty lines because the argument 
m to read() is the number of not empty lines to read! So one must 
subtract the number of empty lines from m above ...


Why on earth was read() changed from the excellent previous version to 
one of no use???



But this does work (m is the number of not empty lines) and is about as 
fast:

--> m = evstr(unix_g("grep -vc ^$ " + filename));

So, together with
--> n = size(evstr(mgetl(filename, 1)), 2);
--> M = read(filename, m, n);

Daniel can get what he wants.

This prevented me from upgrading to Scilab 6 until I found out how to do

evstr is slow with large text vectors, compared to file reading.

  ans  =
9.
--> tic(), M = read(myfile, -1, 9); toc()

So you have to know the file size completely (and when do you?)!

Re: [Scilab-users] How to define the Y Range of plot

[Stefan Du Rietz]

You don't *need* it, of course ;-)
cafix is the handle of your axes from plot() which you got with gca(). 
You can then set the properties of it with the dot method.

Re: [Scilab-users] How to define the Y Range of plot

[Stefan Du Rietz]

That is if you want to change the data_ bounds each time (for very 
different data). I thought that was what you wanted. Otherwise you could 
use it only once after the first plot, or even before if you have no 
other figure open. (thanks Samuel!)

and Y from -2 to +2.
However, plot command didn't work as I expected. Any idea?

cafix.data_bounds = [-0.5,-2;0.5,2];
cafix.tight_limits="on";
cafix.auto_scale="off";
set(gca(),"data_bounds", cafix.data_bounds);


Thanks

Hello,

I would like to define the Y Range of plot. Could you tell me the Scilibe
code to realize this.
If I use the plot command, Y range is automatically set by Scilab.
I would like to set the Y range, e.g. min -10 to Max 20.

Thanks for your advise

Re: [Scilab-users] ?= GUI hel

[Stefan Du Rietz]

figure() is a much more versatile function for the creation of a figure; 
you can set all(?) properties at once.


scf() is useful when you want to change an existing figure.

Hi Antoine, et al - anybody feel free to chime in.

I see the below example uses f=figure() ... instead of f=scf().

What's the reason for this preference?


No particular reason, I just use either scf() or figure().
I think figure() was introduced to ease the transition for Matlab users.
I think they call the same macro with different default values.

Antoine



  From my side, the only difference I can see, is that figure() generates
a place for a GUI with a grey background (background = 33) ... whereas
when I call scf() the background is white (background =  -2). I see the
same list of handles, and all other are also initialized to the same values.

Is there a difference, maybe an invisible one?

Claus

4) I will also look into this. My problem is the steep learning curve.
If you look at the Scilab tutorials you have the good-old Openeering
LHY_Tutorial - it's incredibly complicated and long. Is LHY_Tutorial
using the Model-Viewer-Controller approach? - Maybe the
Model-Viewer-Controller could be presented in a _simple_ tutorial - is
it possible?

Hmm, that would be a good idea.
I'll see whether I can put something together.
The thing is, MVC approach looks rather silly and overengineered on a small 
example.

I have not tried to follow a MWC approach, but here is my attempt at making a 
really simple GUI to just show the basics (see below).
It take numbers from two different types of uicontrols (a slider and an edit) 
and display the sum in a text uicontrol.
To keep things simple, I positioned and sized the uicontrols manually instead 
of using a gridbag.
I also tried to use the fancy syntax for get() and set() that do not require 
calling findobj(), as suggested by Samuel.

Hope it helps,

Also, you should better use get(a, 'propertyName') or set(a,

a.propertyName=value in your callbacks.
I have found that this latter syntax is causing a lot of bug if your 
callback get called really often. I still don't know why.



OK. Now i remember, indeed, that some handle.prop access are badly 
parsed as reading or defining a structure instead of reading or setting 
the (expectedly) defined handle...




I have also noticed all that.

But at last I managed to get it working. ;-)

I had to
1. copy the structure from user_data
2. edit the copied structure
3. set user_data to the edited structure

I think you can achieve what you want by setting ".visible='off'" for all the uicontrols you don't want to show initialy. You can then set  ".visible='on'" after the first call to the callback (or at each call if you are lazy).


I do that and it is very convenient. I also save my GUI data in a 
struct() in the "user_data" of the parent figure of the GUI. Then I 
don't need global variables or even findobj().

Re: [Scilab-users] Scilab 6.0.0 cannot start

[Stefan Du Rietz]

Hello Clément,
I will first tell you some odd things. It appeared that Scilab 5.5.2 
had got exactly the same issue in this computer (I had not used it for 
a while)! I know that the only changes since I last used it were, 
besides installation of Scilab 6, updates of Java and Windows 7 Pro.


I uninstalled Scilab 6, then uninstalled and reinstalled Scilab 5 to 
no avail.


As far as I can imagine, it must be a permissions issue that is not 
present in the Console?


Do you have a hint? Do you still want me to open a bug?

I got Scilab 6 to work in a Windows 10 laptop. However, my loading of 
data with read() took almost half an hour.

From toc() and mprintf():
Loading of data took 26 min 23 sec

In Scilab 5.5.2 it took just over a second.
From toc() and mprintf():
Loading of data took 1.219 sec.

What happened?

Regards
Stefan

[Scilab-users] Scilab 6.0.0 cannot start

[Stefan Du Rietz]

Dear Scilab team,
thank you very much for the new version!

But when I try to start "Scilab 6.0.0" from the Windows 7 Start menu I 
get this message:


"Scilab cannot create Scilab Java Main-Class (we have not been able to 
find the main Scilab class. Check if the Scilab and third-party 
packages are available)."


Only "Java 8 Update 121" is installed.

"Scilab Console" or "Run as Administrator" with "Scilab 6.0.0" does work.

Regards
Stefan

Re: [Scilab-users] case control statement

[Stefan Du Rietz]

Hello Claus,

you put the parentheses wrong:
 elseif or([model==3 model==4])

Hi there

OK, so I converted to elseif (source code at the bottom of my post).
Now Scilab complains like this:

elseif or[(model==3) (model==4)] then // FDD-LOG / CLOG
 !--error 35
Syntax error in a 'if' instruction.
at line  11 of function getq called by :
endfunction

I'm replacing a CASE control with an ELSEIF and using the OR[] to
collect my options. I tested the OR control on the command line,
without problems, so I don't understand what Scilab is complaining about.

Please let me know if you have any idea...

Best regards,
Claus

Here's a code snippet:

// This function, getq, defines the q-values for all models.

if model==1 then // FDD
   //
   // q = 1 - this used to be 1 - beta*ln(w) also for FDD (!?!?)
q = 1;

elseif or[(model==3) (model==4)] then // FDD-LOG / CLOG
 //
 // q = 1 - beta * ln(w) - Scilab log(w) = natural log = ln(w))
q = 1 - gbeta*log(w); // gbeta - it's _not_ LOG model _lambda_

elseif model==2 then // LOG
   //
   // q = 1 - beta*ln(iw)
   //
q = 1 - gbeta*log(%i .* w);

end

Hello Claus,
No it's not possible. It has been suggested here:
http://bugzilla.scilab.org/6503
But chained /elseif /statements do the same in a fully versatile way.
HTH
Samuel
PS: BTW, i don't really understand the interest in the select/case
structure wrt the elseif one.
select/case looks stiffer and less powerful.

Hi there

I'd like to use the "case" control statement to select a few
options. I'm wondering, is it possible for a case to have multiple
options, I mean like this:

select model

case 1,3,4 then

do something

case 2 then

do something

case 5 then

do something

end

Could I define [1 3 4] as a group of options and ask "CASE IN
GROUP" ... or how would I go about and implement this?

Best regards,

Claus

Re: [Scilab-users] Anonymous functions

[Stefan Du Rietz]

Hello Pierre,
is this too simple?

function outer()
  a = 1
  function inner()
mprintf("a = %i (inner: a has the value of the outer function)\n", a)
a = resume(a);
  endfunction
  inner()
  mprintf("a = %i (outer: a has got its new inner value of 2\n", a)
endfunction

Hi Samuel,

Indeed, the behaviour I seek to reproduce is similar to what could be
done with a global variable. Yet I would avoid to resort to global
variables.

From what I've understand about variables scoping in Scilab
(https://wiki.scilab.org/howto/global%20and%20local%20variables),
variables from the above level are only replaced/copied locally when
needed, e.g.

function outer()
  a = 1
function inner()
  disp(a) // a has the value of the outer function
  a = 2   // now a copy is made and a is locally equal to 2
endfunction
  inner()
  disp(a) // a has kept its initial value of 1
endfunction


Hence I guess that the fact that a = 1 in the scope of the outer
function is stored somewhere so that Scilab can retrieve that
information when needed. I'm wondering how it works internally and
whether I could use this to create generic lambda function?

I'm aware that this cannot be done solely in Scilab but requires to
fiddle with the C interface, but I'm curious to experiment.

Pierre

I have actually implemented a similar solution (in the previous

anonymous functions that behaves as in Matlab, i.e. the data of the

In python, the value of the data 'a' is instantiated when the
function is evaluated. Therefore, if the data 'a' changes, the
function changes.

Here I could make something like

deff('y=f(x)','y = a*x')

but then the function will get the value of the variable 'a' of the
current namespace, e.g.

a = 1
function outer(x)
 a = 2
 disp(f(1))
endfunction

f(1) // will give 1
outer(1) // will give 2
a = 3
f(1) // will give 3
outer(1) // will give 2

In this example, I would like f(1) to behave identically
independently of its position.


If i understand correctly your query, the global space is unique and
aims to allow that:
deff('y=f(x)','global a; y = a*x')

This requires the only variable "a" you want to consider been declared
"global a" before some calling point. Actually, i don't see how to
refer to a unique "a" without telling to Scilab which one it must be.

Re: [Scilab-users] Cannot start Xcos

[Stefan Du Rietz]

This line in my loadsci.sce is the culprit:

  r = input("usb2data? [n] ", "s");

The following lines don't matter. This must certainly be a bug?

Stefan

You are launching Xcos properly, but this number of toolboxes looks

Can you please disable their autoload and try to launch Xcos? If it
works, you may want to load them one by one until you can't relaunch
Xcos ; that way we'll know which one is causing the trouble.

Thank you, best regards,

Re: [Scilab-users] SciNotes disappeared

[Stefan Du Rietz]

Hello Paul,
thanks for the answer.

Because I had all my own libraries there, I could not just delete the 
folder.


I deleted scinotesConfiguration.xml and restarted Scilab to no avail.

I made a backup of SCIHOME, deleted it and then restored most of it. 
After that it is again working.


But why did it happen?

Re: [Scilab-users] Windows shell command

[Stefan Du Rietz]

Thanks, I used the switch /LOG to check what happened when I ran the 
dos command from Scilab.


But there is a workaround without an extra file.

My first test command was (the switches are needed when I use it with 
a network server):

-->RCcmd
 RCcmd  =

 ROBOCOPY C:\Users\stefan\Documents\test 
C:\Users\stefan\Documents\new *.txt /TEE /COPY:DT /XJ /XO /FFT /DST /NP


If I add this to the first command, it works, because the output is 
via ECHO:


-->RC2cmd = "FOR /F ""usebackq delims=="" %i IN (`" + RCcmd + "`) DO 
@echo %i"

 RC2cmd  =

 FOR /F "usebackq delims==" %i IN (`ROBOCOPY 
C:\Users\stefan\Documents\test C:\Users\stefan\Documents\new *.txt 
/TEE /COPY:DT /XJ /XO /FFT /DST /NP`) DO @echo %i


But that should be handled by Scilab's functions, at least dos() and 
powershell(), shouldn't it?


Regards
Stefan

Have you tried to display the string A in Scilab?

-->PATH_IMAGEMAGICK = "c:\Path\to\Imagemagick"
 PATH_IMAGEMAGICK  =
 c:\Path\to\Imagemagick

// This is probably not what you want:

I rather agree. Interactive 3D rotation could be activated by default

toolbar when the user need it.

I guess no help, but:

Did you "disp(a.x_location)" and check if the value keeps constant
after updating a.y_location by hand?
Would be interesting to see...never used something like this before.
Best wishes,
Philipp



As I tried to explain, If I set
  a.title.auto_position="on"
after drawlater() where I change the x axis and do many things, and 
not until *after* drawnow() change the y value

  a.title_position(2)=new_vertical_position
then the title gets the correct position: the automatic x value and 
the y value new_vertical_position.


Calixte, please, that must be a bug?

Yes, it does, but the automatic x value should remain if I only
change the y value, shouldn't it?

What about using:
/a.title_position(//1)  = new_horizontal_position/
/a.title_position(2)  = new_vertical_position/
where new_horizontal position = old_horizontal_position if
x-axes does
not change or getting a new value (depending on your data) if the
x-axes changes.


I tried that, but it is very complicated to calculate the
horizontal position so that the title is positioned in the middle ...

And it works if I change the y position after drawnow()!

 If you know where to place x-y-label

 What about:

 a = gca()
 a.x_label.position =
 a.y_label.position =

 works great or me.

 For me as well (i forgot this property), even within
 drawlater/drawnow.
 About a.x_location about which i was thinking : it
works also
 within drawlater/drawnow.
 Ni issue for me (apart reminding ;)

 About the + cross: to avoid it blinking (while axes
stopped
 to), you may update their data instead of deleting and
 recreating it for each iteration, and see the result
(i did
 not try).

Yes, it does, but the automatic x value should remain if I only change 
the y value, shouldn't it?



What about using:
/a.title_position(//1)  = new_horizontal_position/
/a.title_position(2)  = new_vertical_position/
where new_horizontal position = old_horizontal_position if x-axes does
not change or getting a new value (depending on your data) if the
x-axes changes.


I tried that, but it is very complicated to calculate the horizontal 
position so that the title is positioned in the middle ...


And it works if I change the y position after drawnow()!

Stefan

cool...thanks...I managed to have the cross without blinking now
using drawlater() / drawnow() in connection with delete(e). didn't
know "embrassing".

Hello all,
can anybody explain this:
I have a figure f with two axes (and some GUIs). When I move the mouse
with the right button pressed, *one* of the axes gets distorted.


Right-click rotates interactively the axes on which you have clicked.
To restore it (and all), you may do:
f = gcf();
k = f.children.type=="Axes"
f.children(k).view="2d";

SG


Thanks, but it changes the same axes wherever I click! And I would 
like to prevent the possibility to rotate the axes.

[Scilab-users] Strange figure behaviour

[Stefan Du Rietz]

Hello all,
can anybody explain this:

with the right button pressed, *one* of the axes gets distorted.

-->unzoom(f)
or
-->f.event_handler_enable = "off";
does not help.

But my problem is:
1. I change only the x-axis in the axes a
2. I let Scilab set the position with a.title.auto_position="on"
3. I change a.title_position(2)=new_vertical_position
4. unfortunately a.title_position(1) is not updated

Without 3. a.title_position(1) *is* updated!
