[Matplotlib-users] using contourf to plot masked array

2011-02-21 Thread Zhaoru Zhang
Hi, I tried to use contourf to plot an array in which the land values have been masked. However, I found that contourf did not deal with the masking properly. I would expect the masked region to be bounded by the separation line of land and sea, but it actually exceeds that line. I also trie

[Matplotlib-users] Line2D: drawstyle + pick_event

2011-02-21 Thread James Kitchen
'pick_event' fires when I pick on either the marker or the line segment of a Line2D object. But if I change the drawstyle to use steps (steps-pre, steps-post, steps-mid), picking on the line segment is broken. It still seems to think the line is linear. This leads to very strange behavior whe
