Original post from our old UserVoice platform:
I need to define specific areas in my scatterplot.
It would be very helpful to have the possibility of specifying y limits for a band plotted on the x axis and the other way round (that is to specify x limits for a band plotted on the y axis) in such a way that someone can highlight delimited areas (in the form of a rectangle).
As a basic, custom workaround, you can use this: https://jsfiddle.net/BlackLabel/Lkge9x5n
It can be extended to be responsive, to handle multiple axes and more options and operations.
