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.
*args (colormap-spec
, default: rc['image.cmap']
= 'Fire'
) – Positional arguments are colormap names or objects.
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.
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.
refwidth (int
or str
, optional) – The width of each subplot. Passed to subplots
.
ultraplot.figure.Figure
– The figure.
ultraplot.gridspec.SubplotGrid
– The subplot grid.
