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.

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?

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?

similar problems setting usedistiller='xpdf'.
I'm basically an EPS file newbie, so don't be afraid to give me the

I have a feeling its a problem with the font handling. I cant open a file
in inkscape either, the image looks fine but the fonts are missing. Try
setting ps.usedistiller = ghostscript. That converts the file to
low-level postscript, which CS should definitely be able to open. It
worked for inkscape, at least.
Hi Darren,
Hmm, that didn't do it.
That is really surprising to me. How is it that Inkscape can open a postscript
file and Adobe's own software can not?
Simple plots (like simple_plot.py) work with no
distiller step, so it must be something about my more complex plot.
Unfortunately, it's a rather complex menagerie of code that produces the
plot so I'm afraid that if I want to narrow this down, it'll be rather
painful and slow going. I might just stick with the
MPL-EPS-Distiller-PDF-Illustrator toolchain, which seems to work for
the moment.
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.

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!

Fernando (compare this to gnuplot's extensive dashing support).
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 ;)

plot(arange(20), '--', dashes=[5,2,10,5])
Fernando Additionally, I'd like to suggest having a b/w mode,
Fernando where mpl's auto-selection of different colors for
Fernando successive line plots becomes a rotation of dashing
Fernando modes. Gnuplot's EPS backend has exactly this feature,
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 :)
