[Matplotlib-users] hatching problem
Dear Users/Developers
I just installed version 0.99.1.1 since in my previous version (0.98)
I had problems with hatching. It seems though that the same problems
persist in the current version. The attached files reproduce the
problem (a data file and a python short script). Note that hatching is
not present on all green 'CONUPD' fields - but only on few of them.
I will appreciate some hints on how to get by,
Regards
Tomek

I see. But why would I need to set the figure manually when I am drawing with a figure? Is it ever the case where you set one figure, but draw with another?

Re: [Matplotlib-users] Verifying the Use of show()? Win XP
Maybe instead of plot.show() you should do something like:
plot.draw()
raw_input('Press ENTER to exit')
Personally, I also use IDLE on Windows XP to edit my matplotlib files.
However, I never execute in IDLE. I simply double click the file in windows
explorer.

Re: [Matplotlib-users] Figure.draw_artist() bug with Text
Figure.draw_artist is just a convenience function. def draw_artist(self, a): draw :class:`matplotlib.artist.Artist` instance *a* only -- this is available only after the figure is drawn assert self._cachedRenderer is not None a.draw(self._cachedRenderer) And, all the drawing is done by the artist itself. Also, other atists don't fail in this manner if I don't use artist.set_figure(). As far as I can see, it only means that you're lucky with other artists. The reason Text artists needs a reference to the figure is to access the dpi value, as the exception indicates. All artists are meant to be added to an axes (or at least axes, figure, etc. attributes set appropriately) to work correctly.

Re: [Matplotlib-users] trying to Copy plot from one MplWidget canvas to another
Copying a matplotlib canvas (or a figure, or an axes) is not easy. You cannot just rebind it. You need to copy all the hierarchy of underlying artists. Also the attributes of artists need to be adjusted accordingly. And best option in my opinion is just to create another canvas using the code that created the original canvas.

Re: [Matplotlib-users] Verifying the Use of show()? Win XP
Thanks for the clarification. I'm really new to this, and do not know of interactive mode. I presume there's a command to turn it off and on, and possibly an example on how to do it. Is this method of operation with show() mentioned anywhere? The unfortunate present use of show() is that it ties up the shell script, where I happened to have written program output. It's handy to put it there, since it's meant to be interactive. The user is keyboard arrowing through images, and statistical data is placed on the shell window. At the same time he sees a plot of data relevant to the image. He needs to close the plot window before going to the next image. I can probably figure out how to kill the plot window when he does that. My problem with using ipython is that the program I'm modifying is used with IDLE, and people have gotten to use it that way. I had nothing to do with that method of op. I doubt any of the users would be agreeable to using ipython. None of them know Python. The next time the program is released, I may provide it in executable form. I used matlab five years ago, for about two months. To see if it could help me understand MPL, I fired it up, and it's now working. Perhaps the interactive op is explained there. I take it there is no show() there? Interesting mention of non-blocking. In the midst of this dilemma, I started getting socket errors. Using McAffe I found pythonw as blocked. Would that be in anyway associated with the use of show()? I've since changed it to outbound blocking.

Re: [Matplotlib-users] Verifying the Use of show()? Win XP
Thanks. I'll consider it. See my post to John Hunter moments ago as to
why I must use IDLE. Basically, the users are not at all familiar with
Python, and historically the us has been that way for 3-4 years.

Subject: [Matplotlib-users] Verifying the Use of show()? Win XP
I'm sure not making much progress on understanding show(). When used in XP in
IDLE or by file execution (click on file name), it seems to tie up the
executing program. In IDLE, the shell window stops and one must exit the
window.
I'd appreciate it if someone could take any examples
fromhttp://matplotlib.sourceforge.net/index.html and try to execute them
as in the first paragraph to see if they terminate successfully.Let me know
what OS used, hopefully XP, and if you used IDLE or file execution.
I suspect you will find every example there ends with show(). Try putting a
print statement after show() you've done it with the show() the last line.

I suspect this is the problem: numpy-1.4.0 is considered broken and has
been withdrawn. Specifically, it introduces binary incompatibility with

If you go back to the numpy sourceforge site now, I think you will see

the first line. It should be defined. The scrit works just fine after
the proposed changes, even from Pythonwin. Did you completely quit
Pythonwin after the crashes and made sure no corrupted python instance
was left running? Please send the version string of your python

Re: [Matplotlib-users] Runtime Error - Need Advice
I tried something that seems to work consistently - I get the correct plot
figure and the correct log_plot.png file created everytime I run the
script.
From the Start menu, I chose All Programs-Python2.5-IDLE (Python GUI)
instead of All Programs-Python2.5-PythonWin, which creates the Tk Python
Shell. I then open the script file and run it. I think you were right.
Does this make sense?

Thanks for your help. I'll look into ipython.

At this point a Windows user may need to step in. I know nothing about
PythonWin. My suspicion is that this is a problem of dueling event
loops, and one solution would be to use ipython instead of pythonwin.

I suspect this is the problem: numpy-1.4.0 is considered broken and has
been withdrawn. Specifically, it introduces binary incompatibility with
programs compiled against prior versions of numpy, including matplotlib.
If you go back to the numpy sourceforge site now, I think you will see
an earlier version that you can install in place of 1.4.0 (after
removing the latter).

I am not sure what's going on. The script you posted imports pylab in
the first line. It should be defined. The scrit works just fine after
the proposed changes, even from Pythonwin. Did you completely quit
Pythonwin after the crashes and made sure no corrupted python instance
was left running? Please send the version string of your python
installation.

Use pylab.savefig('log_plot'). Also saving the figure to file and
showing it interactively in the same script might involve switching
backends, which might not work as expected.
It is advisable to downgrade to numpy 1.3.

I can now reproduce this. It seems the same old problem that PythonWin
can not reliably run matplotlib because successive runs of the script
use the same interpreter. Ipython should work. Append pylab.close() to
your script; at least it will not crash on the second run.
