Hi. I have done this myself before with no problem, but for some reason I can't figure it out now.

I have a sheet with dates in column A. I have created a line chart to plot column D against the date, no problem.

I want to add column G to the chart with its values on a second axis. Again I have done this before, but I have forgotten the route (I think I'm getting old).

What's the easiest way please, Excel 2007 here

Thx as always. KK
