Here is a simple example that worked for me on a scatter chart with four
series, all separate regions on the sheet. It probably needs work to do what
you want, including bullet proofing and extension to other sheets or
workbooks, which I didn't check. If you can link it to selecting the chart
somehow, then you can also create an "undo" method that links to de-selection
of the chart and returns the cells back to their original formatting. This
would require you to save the original formatting of the cells somehow, a
problem I'll let you figure out!

HTH,
