Re: [Matplotlib-users] matplotlib and cron
Andre, my guess is that there's an attempt made to connect to the
(non-existant) X server. You can disable this by forcing a backend that
doesn't need the X server. Try
import matplotlib
matplotlib.use('Agg')
before the rest of your script.

Hi
I am attempting to generate graphs using matplotlib/pyplot via a cron
process. These scripts work perfectly fine when I am logged in and run
the scripts on the command line, however they fail to run when they are
set up as a cronjob. Even a simplified plotting routine does not work:
from matplotlib.pylab import plot
from matplotlib.pylab import savefig
plot([1,2,3,4])
savefig('test.png')
my crontab is configured like this:
SHELL= /bin/tcsh

[Matplotlib-users] Easiest way of drawing a circle?
Hi, I'm using wxpython with matplotlib, I now have a figurecanvas embedded in my program and I can plot stuff using: a = self.fig.gca() a.plot(x,y) But what is the easiest and fastest way to draw a circle? I saw that the artist class has a draw_arc function.. but I don't know how to use the artist class with my figure canvas.. Like I can't do a.draw_arc() for instance ... Can anyone point me in the right direction? Thanks, Soren - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event. There's still time to save $100.

[Matplotlib-users] pyplot.plotfile - bug report and extension proposal
Hello all,
first of all I want to thank the developers for the plotfile-function.
Nevertheless I would like to report a bug of the function and propose addional
functionality. I added a patch including the following changes:
- circumvent the NameError in the case of len(cols)==1 (N is not defined)
- using fig = gcf() instead of fig = figure() to supress opening a new figure
and therewith allowing to use the user preferred figure
- added keyword argument 'names' to set x/ylabels in the case there are no
names in the csv-file
- changed the plotfile_demo.py accordingly
I would be happy, if this is helpful to others too.
regards Matthias

It looks like matplotlib was built for a different version of iconv than what you have on your machine.

Re: [Matplotlib-users] segmentation fault with pylab
You could try rebuilding matplotlib yourself. There are some OS-X directions here: http://www.astro.washington.edu/owen/BuildingMatplotlibForMac.html This may mean, however, that it won't play nice with other parts of scisoft. But this really is a matter of how and where scisoft was built (which I don't know) and where you're running it.

[Matplotlib-users] Possible to disable wxAgg's smoothing of an image?
Hi, I have a displayed an image with imshow() under wxPython, and it looks great with the WxAgg figure canvas.. but sometimes I want to actually see pixels when I zoom.. and not just a nice smoothed image. Is it possible to disable the smoothing? The way it is now, I will never see square pixels no matter how close i zoom in.. Also, if I want to use matplotlib.patches on a canvas where I can actually see individual pixels, is it possible to only draw on the available pixels showing, and not just make a nice high resolution line that is plotted on top of my image?

You can pass an interpolation parameter to imshow, or set a default in image.interpolation in your matplotlibrc.

[Matplotlib-users] Type 3 fonts
Hi List, I recently subjected some figures to an online 'quality analysis' done by a journal I am submitting a paper to. The analysis stated that my figures (created with mpl's pdf backend, and using whatever default fonts are used) used type 3 fonts, and that I should use type 1 whenever possible. I figured Arial would be a safer bet, but that also drew complaints. I have read a little bit online about the difference between types 1 and 3, but I can't find a description of which font is which type. So what font should I use? -- Chris - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event. There's still time to save $100.

[Matplotlib-users] How to handle different Figures, created from different instances
Hallo, I'm quite new to matplotlib and have a problem, I was searching a solution for the whole day :( The thing is, I want to show different Figures at different states of my main application. So it is not possible for me, to perform the standard procedure, that may looks like: code figure(1) plot(bla) figure(2) plot(bla2) show() /code I have a method, in a class, that should be responsible for drawing a Figure and its content; looks like that: code def drawFigure(self, el): figure(self.__figure) title(self.__headline) plot( el.getXValues(), el.getYValues(),str(el.getColor())+ str(el.getLineStyle())+str(el.getMarkerStyle()) ) show() /code This method exists in several instances of that class, that are created at different times Let I run it this way, the 1st Figure window appears. When this method is called a 2nd time, not 'Figure 2' appears, a window named 'Tk' appears. It is safe that the figure(f) method gets a uniquie number at every time the method is called. I also tried to let all this run in separate threads, using python Threads, but there was no success. Please, can anybody tell me, if there is a solution, to call the show() method more than one time,while my main script is running? The reason why I want to have it this way is, that between different states, some time is elapsing. In this time the user shall have the possibility to watch the figures, and zoom and pan and so on. When the next state is reached, the next Figure window shall appear, while the others are kept on the screen. Thanks, very much.

[Matplotlib-users] Rotating an axes
Can someone tell me if there is a way to rotate an axes instance? I have, figure(1) ax1 = axes([0.0, 0.0, 1.0, 1.0], axisbg='0.95') ax2 = axes([0.2, 0.1, 0.6, 0.8], axisbg='white') and I would like to rotate ax2 30 degrees. It would look something like the attached file. -- The game of science can accurately be described as a never-ending insult to human intelligence. - João Magueijo attachment: rotate.png- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Re: [Matplotlib-users] Toolbar in QT
The toolbar is just a widget so you can do that the same way you show any other widget in Qt. Something along the lines of: - build a widget - add a layout - add the figure widget to the layout - add the toolbar to the layout - connect them together (I forget exactly how but backend_qt.py has all the code that does this) From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Behnam Kamrani Sent: Thursday, May 08, 2008 11:19 AM To: matplotlib-users@lists.sourceforge.net Subject: [Matplotlib-users] Toolbar in QT Hi, First I want to thanks for this amazing Matplotlib. It's fantastic! My newbie question is how I can show the (zoom, pan, etc) toolbar in embedding_in_qt.py example? I have noticed that in animation_blit_qt.py the toolbar is available, but it seems to be done in a different way. Appreciate your help!

Re: [Matplotlib-users] Type 3 fonts
Hi Jouni, JKS Try setting the pdf.fonttype parameter in your matplotlibrc file to JKS 42 and see if the resulting file passes validation. Matplotlib This produces a good-looking pdf. Unfortunately, It'll be a few weeks before I can test it with the online figure check program, since the that manuscript is already submitted and I can no longer update the figures (for now). Once I can try again, I'll let you know. -- Chris - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event. There's still time to save $100.

[Matplotlib-users] axes scale factor not showing
Hi,
When matplotlib uses an axis multiplier, as in x-axis in the script
below, the scale factor is not positioned properly on the figure as is
shown in the attached picture. The 'x1e+30' in the bottom right corner
is clipped unless I enlarge the window.
import Numeric, gtk
import matplotlib
matplotlib.use('GTK')
import matplotlib.figure, matplotlib.axes, matplotlib.backends.backend_gtk
# data
values = Numeric.array([-1e30, -1e30, 0,1,2,3,4,5,6,7,8,9], 'd')
# figure
figsize=(6,3)
figure = matplotlib.figure.Figure(figsize=figsize)
canvas = matplotlib.backends.backend_gtk.FigureCanvasGTK(figure)
axes = matplotlib.axes.Subplot(figure, 111)
figure.add_axes(axes)
axes.hist(values, bins=10)
axes.set_title('X-scale multiplier is hidden', fontsize=10)
# window to display
window = gtk.Window()
window.connect('destroy', gtk.main_quit)
window.add(canvas)
window.show_all()
gtk.main()
I can use the axes position to work I guess but that seems rather
unsatisfactory as I'll have to figure out when it's being displayed or
not, font sizing and spacing blah blah blah.
Is there an easier way around this (or a fix?)? I'm using v0.90.0
Thanks
Tim
