[Matplotlib-users] redefining scatter positions
|

Hello, I am having trouble with scatter plots. I created a scatter plot of just one point: s1 = scatter([1,],[1,]) now I want to move this point after its creation and I'm not sure how to do this. I'm been looking around in teh documentation without any success. Is there something that might be close to the following: s1.set_xydata([2,],[2,]) I can't just clear my axes and redraw the scatter point because it takes too long (there is lots of other stuff on the figure). so I just want to move teh position of the scatter and then do a draw(). any help would be much appreciated! thanks!

But I appreciate your help the WX_AGG environment variable fixed one problem and your information on the linking tool should prove useful to verify that things are getting build correctly. See my post today titled "Workaround for 0.87 WXAgg bug". Apparently according to Onsi there is a bug in the C code, memory is not being allocated correctly.

I believe the new command for anonymous checkout of matplotlib will be: svn co https://svn.sourceforge.net/svnroot/matplotlib/trunk/matplotlib I'll post the developer checkout command on the matplotlib-devel list when I figure it out.

Just make it clear: 1) The binary is build so that it will work with all three 2) The question is what is defined as a dependency when you install it, and what is set as default in matplotlibrc. If so, I'd stick with Numeric as the default. Those of us on the Bleeding Edge of Numpy can still use it, but people's older code should "just work" As a rule of thumb, I'd wait until Travis calls numpy version 1.0 before changing the default. -Chris -- Christopher Barker, Ph.D. Oceanographer NOAA/OR&R/HAZMAT (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chr...@no... --__--__-- Message: 6 From: Vincent Favre-Nicolin To: mat...@li...

It's actually the same command. Only, when committing changes you have t= o=20 supply username and password using, e.g. --username and --password options.= =20 But a subversion GUI (I'm happy with esvn for linux & windows) will do that= =20 for you. What's really nice, there are no more delay between developers and=20 anonymous access.
