Can you utilize a hyperlink as the text for a data point on a chart? if so, how?
The only way I can think of to do this is to take the image that was generated for the chart and turn it into an ImageMap. You would have to know the exact position of each label to do this. It will be a non-trivial task, that's for sure.
