how to overlap 2 graphs/2 scales to relay information

[Jerry C.]

I have 2 graphs, one with sales, and the other with service times, i need a
way to display results on one graph.

You could use the custom Charts and select the line chart on 2 axis. This way you can plot two series of data that have different values on the same chart. best way is to just give it a go.
