- show_channels(*args, N=100, saturation=True, rgb=False, minhue=0, maxsat=500, width=100, refwidth=1.7)[source]¶
Show how arbitrary colormap(s) vary with respect to the hue, chroma, luminance, HSL saturation, and HPL saturation channels, and optionally the red, blue and green channels. Adapted from this example.
colormap-spec, optional) – Positional arguments are colormap names or objects. Default is
int, optional) – The number of markers to draw for each colormap.
bool, optional) – Whether to also show the red, green, and blue channels in the bottom row. Default is
bool, optional) – Whether to show the HSL and HPL saturation channels alongside the raw chroma.
float, optional) – The minimum hue. This lets you rotate the hue plot cyclically.
float, optional) – The maximum saturation. Use this to truncate large saturation values.
int, optional) – The width of each colormap line in points.
str, optional) – The width of each subplot. Passed to
Figure– The figure.
