Using 2 line chart in a ToolTip - cannot select second data source

[NSlater1]

Hi, I have a useful chart set as a ToolTip, which works well when hovering over a matrix I have created.  I am trying - and failing dramatically - to add a second line within this chart from another column of data. Neither in the Y axis or in the secondary Y axis areas...

Frustrating, as I can easily set up a normal chart to do this.  Any help gratefully received !  The data for the line are imaginatevely named Left 2 and Right 2...

For example:
