Dual y axis - how to indicate which axis a trace belongs to

The problem is that there’s no way (apart from hovering over the trace to get the y value) to visually know which y axis a trace belongs to. This becomes a bigger problem when I export the graph as an image.

The legend isn’t indicative either. For eg. the legend keys could be grouped visually according to which axis they belong to.

Did I miss something, is there a way to visually indicate the y axis of a trace? Any workaround if there’s no standard way?

Hey niksoc,

The best way to do that is to add an individual label on each y-axis. You can do this by updating the title attribute of each y-axis. You could also add text to the legend label to specify what axis each color belongs to.
