tool_hover(fig, callback, ref_layer)
fig |
figure to modify |
callback |
a callback to be applied to this tool - either a character string of javascript code or any one of |
ref_layer |
name of the layer that the callback should be applied to |
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.
