Overlay multiple queries ( which has separate unit and scale) in one graph for the same time series..

How to Overlay multiple queries ( like Request count, Size and processing time which has separate unit and scale) in same graph for the same time series…

What was expected to happen?

1 Graph which overlays all the Multiple queries. I am able to do for 2 queries using the Right Y axis but my requirement is more more than 2 queries.
