Lifemap.layer_lines

Lifemap.layer_lines(
    width=None,
    width_col=None,
    color_col=None,
    scheme=None,
    opacity=0.8,
    popup=False,
    label=None,
)

Add a lines layer.

This layer can be applied to data generated by aggregate_num or aggregate_count.

Parameters

Name	Type	Description	Default
width	float | None	Base line width, by default None	None
width_col	str | None	Name of numeric DataFrame column to compute line width, by default None	None
color_col	str | None	Name of numeric DataFrame column to determine line color, by default None	None
scheme	str | None	Color scheme for points color. If color_col is defined, it is the name of an Observable Plot color scale. Otherwise, it is an hexadecimal color value, by default None	None
opacity	float | None	Line opacity as a floating number between 0 and 1, by default 0.8	0.8
popup	bool | None	TODO: doesn’t work for the moment. If True, display informations in a popup when a point is clicked, by default False	False
label	str | None	Legend title for this layer if color_col is defined. If None, the value of color_col is used.	None

Returns

Name	Type	Description
	Lifemap	A Lifemap visualization object.
