Here's a problem that's been driving me nuts, and I finally reduced it to a small self-contained script which can be found at http://gist.github.com/642538. The issue is that the pick_event does not always provide the correct index into the plotted data.
In case this script only bugs out on my machine, let me describe the problem. The callback should highlight whatever point is clicked. This happens correctly with no problems when clicking on 9 out of the 10 points in the figure. But clicking the indicated point on the left-hand side (x[9], y[9]) also causes the indicated point on the top right (x[6], y[6]) to be highlighted as well. Frustratingly, it seems that the numbers themselves are important for reproducing this bug! Specifically, x[9]+=0.01 does not "fix" the bug . . . but x[9] += 0.1 makes the callback work correctly (i.e. only the clicked point is highlighted). I'm guessing this is some sort of tolerance issue somewhere, but I can't find it. possibly-relevant info: matplotlib 1.0.0 numpy 1.3.0 Ubuntu 10.04 64bit thanks, -ryan ------------------------------------------------------------------------------ Nokia and AT&T present the 2010 Calling All Innovators-North America contest Create new apps & games for the Nokia N8 for consumers in U.S. and Canada $10 million total in prizes - $4M cash, 500 devices, nearly $6M in marketing Develop with Nokia Qt SDK, Web Runtime, or Java and Publish to Ovi Store http://p.sf.net/sfu/nokia-dev2dev _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
