Considering how "most people" use X these days, Micah is correct on this.
I don't use a display manager -- I log into the console and start X if I
want to use it.  So, X and all it's children inherit the environment
from my login shell.  I figured setting ENV vars once in .bash_profile
is more efficient than setting it again in every subshell.  (Like it
really matters with modern hardware) 

However, when login is via xdm,kdm etc., the stuff in .bash_profile is
*not* available.

Thanks for pointing that out, Micah.

Huh. I would strongly recommend the opposite. .bash_profile is only
loaded when your shell is a *login* shell; it isn't loaded, e.g., when
you open a terminal emulator in X. Most people (?) are setup so their
.bash_profile automatically imports settings from .bashrc as well, so
global things go in .bashrc, but login-only stuff goes in
.bash_profile.

In my personal experience, the need for me to place anything in
.bash_profile is pretty rare.  A MOTD might be a good example, though.

Alex,

It'd probably be worth checking out the plotutils package

http://www.fsf.org/software/plotutils/plotutils.html

Very stable, very flexible 2-D plotting utilities.  There's a set of 
command-line tools which can handle data in several formats as well as C/C++ 
APIs and a library if you want to compile them into your own programs.  
Produce output in quite a large number of vector and bitmap formats.  The 
installation is of the standard, straightforward configure, make, make 
install variety (i.e., no Makefiles to edit, shell scripts to run, files to 
copy) and there are RPMs and probably Debian binary packages available as 
well.

For 3-D graphics, I haven't found a perfect solution, but the best I've found 
is the dislin package
http://www.linmpi.mpg.de/dislin/

Hope this helps!  Good luck.

Aaron

Alexandra,

In light of the conflicting suggestions, I thought I should mention that
sometimes you're supposed to put the file in .bashrc and sometimes it's
.bash_profile.  It really depends on the setup of your system.  I suggest
trying .bash_profile first, then .bashrc.

Assuming the bash shell, the command is:
export PLOTICUS_PREFABS=/some/path

That will be set until you exit the shell.  If you want it on at reboot
time, stick it in your ~/.bash_profile.  You'll need to do this if you
you want to run ploticus by clickety clicking on a menu item.

Assuming you use bash, export PLOTICUS_PREFABS='' will do this once.
To set the variable in all new shells, add the appropriate export
VARIABLE_NAME= to ~/.bashrc.

dylan, that's pretty cool (or rather, looking at the air temp, pretty
hot.  arf arf).

this looks like a command based tool, like gnuplot, but with more
impressive output.

how large is the command set (not data) to produce a graph like this?
if it's only a few lines, can you post it to show what using ploticus
looks like?

there's also scilab which is supposed to be very nearly like matlab and

i use gnuplot, of course, but the whole question of data presentation
relies on the type of data you want to show, which you haven't

used excel once or twice in my life, but i've been told that gnumeric is
very faithful to excel.  it sure looks the same.  in fact, on the
gnumeric list, i once reported a bug related to the graphing system and
was told by a developers that this was to make gnumeric compatible with
an existing bug in excel...

Re: [vox-tech] Linux graphing software?

2003-05-30 Thread Jonathan Stickel 
It won't be long before someone recommends gnuplot.  I haven't used it 
much due to my reliance on Matlab (which runs nicely in Linux, but 
certainly isn't "free").  Another option is Octave, an open source 
program very much like Matlab, which happens uses gnuplot for plotting.

Anyway, my contribution to this thread is to recommend xfig for 
"post-processing" of plots as well as drawing original diagrams.  I have 
found it invaluable in touching up Matlab exported plots, such as 
modifying axis labels, etc.  xfig exports in numerous formats, some of 
which import very nicely into LaTeX.  In particular, I use the export 
option "combined PS/LaTeX", allowing me to use LaTeX syntax for the text 
in the figures.

out there has some recommendations of some relatively accessible Linux
softward for creating pretty scatterplots of real data.  In the past I've
tended to use MSExcel for this sort of thing but would like to shake that
habit for obvious reasons.
Thanks,
