| 158212793 | MDU6SXNzdWUxNTgyMTI3OTM= | 866 | Drawing only one contour | 7300413 | closed | 0 | 8 | 2016-06-02T18:50:36Z | 2016-07-20T17:16:27Z | 2016-07-20T17:16:27Z | NONE | Hello, I was trying to draw only a single contour by passing levels=[0], and nothing gets plotted. I checked utils.py, and the logic used to calculate n_colors in _build_discrete_cmap gives n_colors=0, since it will first set extend to 'neither', and so ext_n = 0, and n_colors = len(levels) + ext_n - 1 I'm not sure, but this might be the issue. Another issue, which might be unrelated, is when I'm trying to draw two contours. It plots only one contour, and it will plot two contours only if I set norm=None. Any suggestions? TIA, Joy |
