Last active January 3, 2017 14:11
wxmplot features that could be integrated into matplotlib

New features

  • Expose artist zorder.
  • Toggle legend (via checkbox rather than click). Add recipe for legend that allows toggling artist visibility.
  • Change normalization class.

Already present

  • Change normalization bounds.
  • Change image smoothing.

Not suitable?
