[Matplotlib-users] backends issue
I have a problem with backend: by default it was Agg; i tried to change the file .matplotlibrc and to put GTKAgg, but as I import pylab I got these errors: from pylab import * Traceback (most recent call last): File stdin, line 1, in ?

That works well enough (I believe that I originally had editted backend_bases to circumvent the format_coord call--clearly not the best solution)! I don't know of a good reason to *not* use the axis formatting, but perhaps an rcparam could control this? I don't know what the historical reason for the present default is, but one candidate is speed: the coordinate numbers get reformatted and printed at a great rate as the cursor moves across a plot, so one might not want to have the formatting done by a big chunk of python code. format_data_short will typically be faster than format_data. Here is the reason format_data_short was added: the x,y coordinates of the cursor used to be printed to 10 digits, something I added when I was working out the offset ticklabels for the x and y axis. These coordinates, when rendered into the toolbar, were causing the figure window to resize to make room for the numbers in the toolbar. format_data is also used to format the ticklabels, so John suggested the new method. At the time, we needed a quick work around. Maybe it's time to give it another look, and see if there is a better long-term solution. Darren - Take Surveys. Earn Cash.

Of course, that wont' do it if I dont' get around to fiing a bug report! wxPython includes a wxversion module that lets one select whihc version of wxPython you want run, if more than one is installed. It might be nice if those calls could get put into MPL somewhere, so that when MPL is built against a given version, that version will be run. If someone can do a Windows build against a wxPython 2.8 version (and Python 2.5) I could do some testing. Is there a list of what the problems are? Werner - Take Surveys. Earn Cash.

Re: [Matplotlib-users] Maximized vs non-maximized output
Okay, I tried saving using the postscript format, and I end up with the ugly plot also. In fact, if I maximize the plot and then save as .ps file, I get ugly plot as well. So, saving it in PS made no difference - that part is correct but it means I end up with the same font, and dimension as the non-maximized version. Somehow, if I maximize the plot using the show() command, maximize it first, then save it (in png format), I end up with a very nice looking plot. I just wish there is a simple way to accomplish that in batch mode.

Re: [Matplotlib-users] display GUI scientific notation
Hi, I would like to add another annoying aspect of the digits in the GUI: When a log axis is used the displayed numbers looks like 10^-8.23 which is definitely not human readable. Do somebody know a quick fix to obtain something like 5.89e-9 or 5.89x10^-9 ? Thanks, David - Take Surveys. Earn Cash.

The WXAgg backend itself should still function without _wxagg.so, which exists slowly to speed up the Agg/wx.Image/wx.Bitmap tango. I tried to get it up and running on OSX with wxPython 2.8 earlier today but was quickly stymied by an inscrutable problem with wxPyConstructObject(). Since I'd like to start moving away from using a C++ extension in the backend, I'm going to try to re- implement its functionality using the new wx.BitmapFromBufferRGBA(). The other I know about is some oddities with the toolbar on OS-X -- I think those are OS-X only issues. Once I have the WXAgg accelerator straightened out, I'll see if I can reproduce and fix this problem. Ken - Take Surveys. Earn Cash.
