Re: [Matplotlib-users] py2exe and matplotlib errors when executing exe
Thanks, I changed the matplotlibrc file to use the WXAgg backend and then had to copy the file into the mpl.get_configdir() and in my local working dir for it to work. The file runs however a python error screen pops up and then closes without giving me the chance to read it, anybody know how to stop the window from closing so quickly Thanks Marco Michael Droettboom-3 wrote: It should only try to import that backend when configured to do so.

Re: [Matplotlib-users] Plotting single marker point at zoomed level
Thanks for that, I already have a button to enable picking mode and the original post shows that I have already tried the copy background/restore/blit, however I must have been doing something wrong. Pehaps you can point out what the issue was ro where I was going wrong John Hunter-4 wrote: On Wed, May 28, 2008 at 7:10 AM, New2Python [EMAIL PROTECTED] wrote: One issue that I find now is that the removed marker is not redrawn as removed, in other words, all the original markers remain drawn whether or not the datapoints exist in the array.

I would have a picking mode which is enabled by a key-stroke or button press, and when the mode is enabled, you can copy the background using the copy_background/restore region/blit techniques discussed at http://www.scipy.org/Cookbook/Matplotlib/Animations. Then you can mark your vertices and just draw the vertex marker line over the background. Alternatively, you can use the clipped line approach I pointed you to in my prior post to only plot the vertices in the viewport. You will have to do a little bookkeeping to translate the marked vertices in the viewport to the ones in the original dataset. Unfortunately, I don't have time to write the complete example right now... JDH - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] Plotting single marker point at zoomed level
Thanks for that, the canvas.draw() function redraws the graph. I had to add the autoscale_on=False to the add_subplot() to stop the graph from autoscaling. One issue that I find now is that the removed marker is not redrawn as removed, in other words, all the original markers remain drawn whether or not the datapoints exist in the array. How can I remove the marker I don't want anymore withought doing a clf() call because I can have over 300,000 datapoints and the redraw will take ages Thanks for the link to the clipping code, that will come in handy.

I have a line plotted and I need to be able to mark selected data points on the line. I am If you are frequently changing the zoom level, as it looks like you are, the copy background/restore region/blit idiom is probably not the right one for you, since the background is assumed fixed. You can simply force a draw at any time by doing fig.canvas.draw() w/o having to zoom out or resize to trigger a draw. So after doing the self.marker.set_data call, I would do fig.canvas.draw I thought this would be a generally useful thing to do (maintain a list of toggleable selected vertices) so I added some support. Here is some example code to highlight the selected markers: The matplotlib.lines.VertexSelector maintains a list of selected line vertices using the line picker property. If an unselected vertex is clicked, it is selected, and if a selected vertex is clicked, it is unselectedit. Classes which inherit from the VertexSelector should override the process_selected method to do something with the selected vertex. This example just highlights them with red markers.

Re: [Matplotlib-users] from pylab import nx?
Hi All, I have the same issue, is there a fix to this Michael Droettboom-3 wrote: Eric Firing wrote: Chris Withers wrote: Hi All, A few of the units demos include the lines: from pylab import nx ...but this import errors for me. Why is that? If you are referring to scripts in the matplotlib/examples/ subdirectory then you must have a version in which some of those scripts had not been brought up to date with the rest of matplotlib. (Historically, this has often been the case--only a subset of the examples are maintained. Right now, for example, simple3d.py is broken. 3D plotting is itself unmaintained, so there is little incentive to do anything about the example.) In the svn version there are no lines importing nx. This was an abbreviation for the numerix module, which was a compatibility wrapper for the three different numeric packages (Numeric, numarray, and numpy) until numpy was fully developed, rendering Numeric and numarray obsolete. Slightly OT, but if matplotlib is participating in any sort of internship projects (Google Summer of Code etc.) that would be a great student project -- to clean up all the examples, removing dead ones, editing for consistency etc. Cheers, Mike - This SF.net email is sponsored by: Microsoft Defy all challenges.
