show_channels(*args, N=100, rgb=True, saturation=True, minhue=0, maxsat=1000, axwidth=None, width=100)¶
Shows 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.
*args (colormap-spec, optional) – Positional arguments are colormap names or objects. Default is
N (int, optional) – The number of markers to draw for each colormap.
rgb (bool, optional) – Whether to also show the red, green, and blue channels in the bottom row. Default is
saturation (bool, optional) – Whether to show the HSL and HPL saturation channels alongside the raw chroma.
minhue (float, optional) – The minimum hue. This lets you rotate the hue plot cyclically.
maxsat (float, optional) – The maximum saturation. Use this to truncate large saturation values.
width (int, optional) – The width of each colormap line in points.
axwidth (int or str, optional) – The width of each subplot. Passed to
Figure– The figure instance.
