tool_hover {rbokeh}R Documentation

Add "hover" tool to a Bokeh figure

Description

Add "hover" tool to a Bokeh figure

Usage

tool_hover(fig, callback, ref_layer)

Arguments

fig

figure to modify

callback

a callback to be applied to this tool - either a character string of javascript code or any one of debug_callback, shiny_callback, console_callback, custom_callback

ref_layer

name of the layer that the callback should be applied to

Note

Tools can be easily specified as a vector of tool names in the tools argument when instantiating a figure. In this case, they are added with defaults. Explicitly calling these tool_ functions will manually add the tool to a figure and allow additional specification of parameters.
