lets_plot.stat_summary

lets_plot.stat_summary(mapping=None, *, data=None, geom=None, position=None, show_legend=None, sampling=None, tooltips=None, orientation=None, fun=None, fun_min=None, fun_max=None, quantiles=None, color_by=None, fill_by=None, **other_args)

Display the aggregated values of a single continuous variable grouped along the x axis.

Parameters:

mappingFeatureSpec

Set of aesthetic mappings created by aes() function. Aesthetic mappings describe the way that variables in the data are mapped to plot “aesthetics”.

datadict or Pandas or Polars DataFrame

The data to be displayed in this layer. If None, the default, the data is inherited from the plot data as specified in the call to ggplot.

geomstr, default=’pointrange’

The geometry to display the summary stat for this layer, as a string.

positionstr or FeatureSpec, default=’identity’

Position adjustment. Either a position adjustment name: ‘dodge’, ‘dodgev’, ‘jitter’, ‘nudge’, ‘jitterdodge’, ‘fill’, ‘stack’ or ‘identity’, or the result of calling a position adjustment function (e.g., position_dodge() etc.).

show_legendbool, default=True

False - do not show legend for this layer.

samplingFeatureSpec

Result of the call to the sampling_xxx() function. To prevent any sampling for this layer pass value “none” (string “none”).

tooltipslayer_tooltips

Result of the call to the layer_tooltips() function. Specify appearance, style and content.

orientationstr

Specify the axis that the layer’s stat and geom should run along. The default value (None) automatically determines the orientation based on the aesthetic mapping. If the automatic detection doesn’t work, it can be set explicitly by specifying the ‘x’ or ‘y’ orientation.

fun{‘count’, ‘sum’, ‘mean’, ‘median’, ‘min’, ‘max’, ‘lq’, ‘mq’, ‘uq’}, default=’mean’

Name of function computing stat variable ‘..y..’. Names ‘lq’, ‘mq’, ‘uq’ corresponds to lower, middle and upper quantiles, default=[0.25, 0.5, 0.75].

fun_min{‘count’, ‘sum’, ‘mean’, ‘median’, ‘min’, ‘max’, ‘lq’, ‘mq’, ‘uq’}, default=’min’

Name of function computing stat variable ‘..ymin..’. Names ‘lq’, ‘mq’, ‘uq’ corresponds to lower, middle and upper quantiles, default=[0.25, 0.5, 0.75].

fun_max{‘count’, ‘sum’, ‘mean’, ‘median’, ‘min’, ‘max’, ‘lq’, ‘mq’, ‘uq’}, default=’max’

Name of function computing stat variable ‘..ymax..’. Names ‘lq’, ‘mq’, ‘uq’ corresponds to lower, middle and upper quantiles, default=[0.25, 0.5, 0.75].

quantileslist of float, default=[0.25, 0.5, 0.75]

A list of probabilities defining the quantile functions ‘lq’, ‘mq’ and ‘uq’. Must contain exactly 3 values between 0 and 1.

color_by{‘fill’, ‘color’, ‘paint_a’, ‘paint_b’, ‘paint_c’}, default=’color’

Define the color aesthetic for the geometry.

fill_by{‘fill’, ‘color’, ‘paint_a’, ‘paint_b’, ‘paint_c’}, default=’fill’

Define the fill aesthetic for the geometry.

other_args

Other arguments passed on to the layer. These are often aesthetics settings used to set an aesthetic to a fixed value, like color=’red’, fill=’blue’, size=3 or shape=21. They may also be parameters to the paired geom/stat.

Returns:

LayerSpec

Geom object specification.

Notes

Computed variables:

• ..y.. : result of calculating of fun.

• ..ymin.. : result of calculating of fun_min.

• ..ymax.. : result of calculating of fun_max.
