Is there a way to retrieve all the selected legends in a graph. The intention behind this is, based on the legends, I have to derive different plots. For instance, if you select two legends, then I have to plot the relationship between those two variables. I have binded the plotly legend event, so whenever I click the legend name, the event gets triggered. Unfortunately, I couldn’t get the legend name or names.
Could you clarify what you mean by “legends”. Plotly graph can only have one legend per graph, so I suspect you mean the legend items, like Data and Fit below
Clicking on a legend item change the traces’
visible attribute, so to list all visible traces on the graph, you could do something like:
var gd = document.getElementById(/* id of your graph div */) gd.data.map(trace => trace.visible)
