Add shapes to plotly plot

Modifies the layout object of an existing plot to include a new shape.

Usage

add_shapes(p = plotly::last_plot(), shapes)

Arguments

p

The plot to which the shape should be added. Default is the last_plot().

shapes

A list of attributes that specify a shape. Note that only one shape can be added for each call, but to be consistent with the shapes argument to plotly::layout(), we use the same plural.

Details

This function adds a shape to the layout element of a plotly plot. Type schema() in the console and expand the list for layout > layoutAttributes > shapes for details on how to specify a shape. A convenient Pmetrics helper function to add line shapes is ab_line. Other shapes such as circles, rectangles and paths can be added, but must be done manually as outlined in the plotly schema documentation. An example of a circle shape is below in examples.
