) -> LayerSpec

Evaluate fun at x values and draw the result.

Parameters:

mapping (FeatureSpec, default: None ) –

Aesthetic mapping; x may name a column of data or be a list of values.
data (DataFrame or dict, default: None ) –

Data holding the x column; a y column with the results is added.
stat (str, default: "identity" ) –

Stat of the layer.
geom (str, default: "line" ) –

Geom of the layer.
fun (callable, default: None ) –

Function of one number; None gives an empty y.
xlim (list of float, default: None ) –

[low, high] of the evaluated x range when x is not mapped (default [0, 1]).
n (int, default: None ) –

Number of evaluated points in xlim (default 512).
position (str or FeatureSpec, default: None ) –

Position adjustment: a name such as "dodge" 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 ) –

A legend key for this layer, as in lets_plot; not supported yet (ggrust warns).
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").
**other_args (Any) –

Constant aesthetics and the geom's options, as in lets_plot.

Returns:

LayerSpec –

The layer.
