lets_plot.stat_sum#
- lets_plot.stat_sum(mapping=None, *, data=None, geom=None, position=None, show_legend=None, sampling=None, tooltips=None, color_by=None, fill_by=None, **other_args)#
Sum unique values.
- 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=’point’
The geometry to display the sum 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.
- 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:
..n.. : number of points with same x-axis and y-axis coordinates.
..prop.. : proportion of points with same x-axis and y-axis coordinates.
..proppct.. : proportion of points with same x-axis and y-axis coordinates in percent.
stat_sum() understands the following aesthetics mappings:
x : x-axis coordinates.
y : y-axis coordinates.
In addition, you can use any aesthetics, available for the geometry defined by the geom parameter.
