lets_plot.scale_x_discrete¶
- lets_plot.scale_x_discrete(name=None, *, breaks=None, labels=None, limits=None, expand=None, na_value=None, reverse=None, format=None, position=None)¶
Discrete position scale x.
- Parameters
- 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
A vector specifying the data range for the scale and the default order of their display in guides.
- expandlist
A numeric vector of length two giving multiplicative and additive expansion constants. The vector size == 1 => only multiplicative expand (and additive expand by default). Defaults: multiplicative = 0, additive = 0.2.
- na_value
Missing values will be replaced with this value.
- reversebool
When True the scale is reversed.
- 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.
- positionstr
The position of the axis:
‘left’, ‘right’ or ‘both’ for y-axis;
‘top’, ‘bottom’ or ‘both’ for x-axis.
- Returns
- FeatureSpec
Scale specification.
