The problem is that many utilities don't return anything, they just print to stdout (setp is one such tool). Which means that we'd need to capture all of stdout and have it available for further processing always, in a non-blocking way (so typing 'ls' doesn't make you wait forever before printing). This is really pushing ipython far into the shell territory, albeit in a manner that would be very useful. I'll forward this to the ipython-dev list, to see if Ville and Walter (the brains behind the fancy ipipe) want to pick this ball up and run with it. I'm now pretty much only working with Brian on the new branch. Incidentally, this would bring ipython much closer to Microsoft's Monad shell model: http://arstechnica.com/guides/other/msh.ars Ever since that review came out, I've thought that python/ipython already has 90% of those tools, save a proper (but better) pipe-like model for chaining object results. With a bit of time investment, this could certainly be done. Cheers, f - Using Tomcat but need to do more? Need to support web services, security?

Are you aware of the "dashes" property, which allows you to set the
exact dash pattern you want. It's an arbitrary length sequence of
alternating ink-on, ink-off, in points
In my humble defense, the fact that this is barely mentioned in the
pylab tutorial, not at all in the plot docstring, and also not in
Perry's tutorial, may have something to do with my not knowing about
it ;)

This seems like a good idea -- if you define a nice sequence of dashes
you want to cycle through, I'll build the rest of the infrastructure
and make a figure property like iscolor.
Here's a specific, backwards-compatible proposal: why not add a new
format string type, '-N', with N running 0-9, and '-0' being identical
to a '-' (i.e., a continuous line). I think that having easy access
to continuous plus 9 dashing patterns should be enough for most
purposes (a plot with more than 10 traces on it is just unreadable
anyway). This mode also makes it code-friendly, so that one can
easily select any of the patterns with code of the type
'-%s' % n
where n is being looped over, or a key from a dict, whatever.
I'm not quite sure what the best 9 patterns should be, so I'm
attaching a script to make it easy to test a bunch of them in a
hurry. This can help us find 9 distinctive ones (the gnuplot ones are
good, but I think we can do better), to put them into this basic list.
The little script can also be added to the examples dir to showcase
the 9 basic patterns once selected (and you can make a figure for the
tutorial with it :)

Thanks for these. In playing with this, both for my needs and to try
and contribute something for a permanent solution, I found something
really strange. Try running the following code in pylab:
"""Simple dashing test."""
import numpy as N
import pylab as P
dashes= { 0:(1,0),
1:(2,2),
2:(10,4),
3:(10,4,4,4),
4:(10,2,2,2),
5:(15,2,6,2) }
y = N.ones(10)+N.rand(10)
P.figure()
dashnums = dashes.keys()
dashnums.sort()
for d in dashnums:
P.plot(y,dashes=dashes[d])
# Bug??? Using this, nothing gets displayed:
y += 1
# But with this, it works fine:
#y = y+1
P.show()
# EOF
Uncomment the 'y=y+1' option, and all works fine. Here's where the
problem may be coming from, just try this in a terminal:
y = 1.0*arange(10)
plot(y)
y += rand(10)
show()
There are actually two issues here, one is definitely a bug, the other
one could be construed as a feature (albeit a surprising one):
- bug: that the script above doesn't display anything with current
SVN. I don't know why.
- feature?: that mpl holds on to the actual numpy memory buffer, so if
an array is modified in-place, any subsequent window update will
modify the plot. I can actually see this being quite useful for
monitoring a region of memory, though it can cause surprising behavior
if you are just trying to get successive plots. I guess I'm squarely
+1/-1 on how much I like it :)
I'll work a bit more on the dashing and send something later...
Cheers, and thanks for the hints!

Well, I didn't try Inkscape on it. My version of Inkscape doesn't seem
to import EPS files. How are you doing it. I've tried pstoedit to

Re: [Matplotlib-users] bug?
Some change have been introduce in matplotlib? Because I used this sequence before and it was working. I'm a little bit surprise by the fact that the rgb sequence must be three numbers between 0 and 1. Generally rgb sequence are between 0 and 255, aren't they? http://homepage.mac.com/jakesan/DHP/page0/page3/page3.html And so my sequence is correct in this definition but yes false in the actual matplotlib definition but in this case an explicit error message must be given to tell that RGB color doesn't respect the general convention and must be between 0 and 1 Regards, N.

That is really surprising to me. How is it that Inkscape can open a postscript
file and Adobe's own software can not?

If you get time, you might edit the postscript file by hand and comment out
large sections of the code, and try importing those modified files.

[Matplotlib-users] Install
Dear All, i was wondering if they are a binary package for matplotlib for macos10.3 with python2.4, and the last version of numpy. The one i found is only the 0.82 and required numeric. Or do i have to build from source. I am a bit confused as the last source file still talk about numeric and numarray. Thanks for your help Brice - Using Tomcat but need to do more?

Re: [Matplotlib-users] Improved dashing for black and white plots?
On this topic, here is something I used the other day (just some
different dash sequences):
e, = plot(x, y, 'k', label=r'$\theta_3=%1.2f$'%(th3))
setp(e, dashes={0:(1,0), 1:(2,2), 2:(10,4), 3:(10,4,4,4), 4:(10,2,2,2),
5:(15,2,6,2)}[i])
Maybe we should just blatantly copy the gnuplot sequence, although the
sequence might be gpl'ed!
One question which arises is that it wasn't clear what to set dashes to
to get a solid line. I ended up doing the 0: case above i.e. (1,0), but
I suspect this isn't ideal because it might generate lots of unwanted
line segments. I think I tried None and (1) and it didn't work. Perhaps
(999,0) would be better?

Re: [Matplotlib-users] bug?
An rgb colorspec in matplotlib must be a sequence of three numbers between zero and one, so the problem is that you are indeed giving an invalid rgb arg. I think perhaps you grabbed an error message from a different instance of this error; when I try it, I get an error message that correctly gives the invalid arg that was supplied: ValueError: to_rgb: Invalid rgb arg "(120, 120, 120)" to_rgb: Invalid rgb arg "(120, 120, 120)" Eric [EMAIL PROTECTED] wrote: > Hello, I have a problem with the svn version of matplotlib.
