lets_plot.scale_hue¶
- lets_plot.scale_hue(aesthetic, *, h=None, c=None, l=None, h_start=None, direction=None, name=None, breaks=None, labels=None, limits=None, na_value=None, guide=None, trans=None, format=None)¶
Qualitative color scale with evenly spaced hues for the specified aesthetics.
- Parameters
- aestheticstr or list
The name(s) of the aesthetic(s) that this scale works with.
- hlist
Range of hues (two numerics), in [0, 360].
- cint
Chroma (intensity of color), maximum value varies depending on.
- lint
Luminance (lightness), in [0, 100].
- direction{1, -1}, default=1
Direction to travel around the color wheel, 1=clockwise, -1=counter-clockwise.
- namestr
The name of the scale - used as the axis label or the legend title. If None, the default, the name of the scale is taken from the first mapping used for that aesthetic.
- breakslist
A vector specifying values to display as ticks on axis.
- labelslist of str
A vector of labels (on ticks).
- limitslist
Continuous scale: a numeric vector of length two providing limits of the scale. Discrete scale: a vector specifying the data range for the scale and the default order of their display in guides.
- na_value
Missing values will be replaced with this value.
- guide
Guide to use for this scale. It can either be a string (‘colorbar’, ‘legend’) or a call to a guide function (guide_colorbar(), guide_legend()) specifying additional arguments. ‘none’ will hide the guide.
- trans{‘identity’, ‘log10’, ‘sqrt’, ‘reverse’}
Name of built-in transformation.
- formatstr
Define the format for labels on the scale. The syntax resembles Python’s: ‘.2f’ -> ‘12.45’ ‘Num {}’ -> ‘Num 12.456789’ ‘TTL: {.2f}$’ -> ‘TTL: 12.45$’ For more info see https://lets-plot.org/pages/formats.html.
- Returns
- FeatureSpec or FeatureSpecArray
Scales specification.
Notes
Define qualitative color scale with evenly spaced hues for the specified aesthetics.
