lets_plot.geom_jitter¶
- lets_plot.geom_jitter(mapping=None, *, data=None, stat=None, position=None, show_legend=None, sampling=None, tooltips=None, width=None, height=None, **other_args)¶
Display jittered points, especially for discrete plots or dense plots.
- 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 DataFrame 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.
- statstr, default=’identity’
The statistical transformation to use on the data for this layer, as a string. Supported transformations: ‘identity’ (leaves the data unchanged), ‘count’ (counts number of points with same x-axis coordinate), ‘bin’ (counts number of points with x-axis coordinate in the same bin), ‘smooth’ (performs smoothing - linear default), ‘density’ (computes and draws kernel density estimate).
- positionstr or FeatureSpec
Position adjustment, either as a string (‘identity’, ‘stack’, ‘dodge’, …), or the result of a call to a position adjustment function.
- show_legendbool, default=True
False - do not show legend for this layer.
- samplingFeatureSpec
Result of the call to the sampling_xxx() function. Value None (or ‘none’) will disable sampling for this layer.
- tooltipslayer_tooltips
Result of the call to the layer_tooltips() function. Specifies appearance, style and content.
- widthfloat, default=0.4
Amount of horizontal variation. The jitter is added in both directions, so the total spread is twice the specified parameter. Typically ranges between 0 and 0.5. Values that are greater than 0.5 lead to overlapping of the points.
- heightfloat, default=0.4
Amount of vertical variation. The jitter is added in both directions, so the total spread is twice the specified parameter. Typically ranges between 0 and 0.5. Values that are greater than 0.5 lead to overlapping of the points.
- 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
The jitter geometry is used to create jittered points. The scatterplot is useful for displaying the relationship between two discrete variables.
geom_jitter() understands the following aesthetics mappings:
x : x-axis value.
y : y-axis value.
alpha : transparency level of a point. Understands numbers between 0 and 1.
color (colour) : color of a geometry. Can be continuous or discrete. For continuous value this will be a color gradient between two colors.
fill : color to paint shape’s inner points. Is applied only to the points of shapes having inner points.
shape : shape of the point.
size : size of the point.
