Hoverinfo for bar chart with multiple y axes

[sagarman]

I have a bar chart with two y axes and a common x axis. How can I display the information from both y axes upon hovering the chart? What should I set the ‘hoverinfo’ to in respective traces?

Can you share a reproducible example?

I can see the same thing. But it is not very intuitive for the purpose. Pretty confusing with the random gaps.
