) -> LayerSpec

Points at each distinct (x, y), sized by the number of rows there (stat="sum").

The stat computes ..n.. (rows, or summed weight, at the location), ..prop.. (n over the group's total) and ..proppct.. (the same in percent); size is mapped to ..n.. by default.

Parameters:

  • mapping (FeatureSpec, default: None ) –

    Aesthetic mapping from aes(): x, y (required), color, fill, size, shape, alpha, stroke, weight.

  • data (DataFrame or dict, default: None ) –

    Layer data; inherits the plot data when None.

  • stat (str, default: None ) –

    Statistical transformation, by name; "sum" when None.

  • position (str or FeatureSpec, default: None ) –

    Position adjustment: a name such as "jitter" or a position_*() spec.

  • show_legend (bool, default: None ) –

    False hides this layer from the legend.

  • inherit_aes (bool, default: None ) –

    False ignores the plot's default mapping for this layer.

  • manual_key (str or FeatureSpec, default: None ) –

    This layer's key in a manual legend: a label, or layer_key().

  • sampling (str or FeatureSpec, default: None ) –

    lets_plot sampling; accepted and ignored, as ggrust draws every row.

  • tooltips (FeatureSpec or list of str, default: None ) –

    Tooltip content: layer_tooltips(), a list of column names, or "none" to disable tooltips (HTML output).

  • color_by (str, default: None ) –

    Aesthetic the color scale applies to ("color" or "fill").

  • fill_by (str, default: None ) –

    Aesthetic the fill scale applies to ("color" or "fill").

  • na_rm (bool, default: None ) –

    True removes rows with missing values silently; otherwise they are removed with a warning.

  • **other_args (Any) –

    Constant aesthetics such as color="red" or alpha=0.5.

Returns:

  • LayerSpec –

    The layer.

Examples:

>>> from ggrust import *
>>> data = {"cylinders": [4, 4, 6, 8, 4, 6, 8, 8], "gears": [4, 4, 4, 3, 5, 4, 3, 3]}
>>> plot = ggplot(data, aes("cylinders", "gears")) + geom_count()
