get_colormap
(name, reverse=False, set_bad=None)[source]¶ Get a colormap given its name.
Parameters: - name (str) – The name of the colormap. See the Notes for special values.
- reverse (bool) – Pass True to reverse the colormap.
- set_bad (str, optional) – Color to set as the
set_bad
color on the returned colormap. This is commonly used to represent NaN or undefined values.
Returns: The requested colormap.
Return type: matplotlib.colors.Colormap
Notes
If
name
matches a built-in matplotlib colormap, that colormap will be returned. Ifname
matches one of the following special values, the corresponding specialized colomap will be returned:- ‘obs_over_exp’: a colormap for visualizing fold changes in interaction frequencies
- ‘is’: a colormap for plotting interaction score heatmaps
- ‘obs’: a colormap for visualizing observed interaction frequencies
- ‘bias’: a colormap for plotting bias factor heatmaps
You can append ‘_bad_<color>’ to any of these to set the set_bad color, for example: ‘abs_obs_bad_green’
