# lets_plot.scale_y_continuous¶

lets_plot.scale_y_continuous(name=None, breaks=None, labels=None, limits=None, expand=None, na_value=None, trans=None, format=None)

Continuous position scale y.

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 numeric vector of positions (of ticks).

labelslist of str

A vector of labels (on ticks).

limitslist

A numeric vector of length two providing limits of the scale.

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 = 0.05, additive = 0.

na_value

Missing values will be replaced with this value.

trans{‘identity’, ‘log10’, ‘sqrt’, ‘reverse’}

Name of built-in transformation.

formatstr

Defines 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

Scale specification.
