I am developing an application in which I would like the user to be able to click on a chart and have the application detect whether the click has occurred over a specific piece of text. For example, I have multiple lines on a chart with two y-axes, and I have the titles of the series stacked up at the top of the chart. I would like the user to be able to click one of the titles which would then cause the corresponding series to switch to the other axis. Unfortunately I still cannot figure how to retrieve the area that a piece of text fills on the chart. (in case it makes a difference, note that the chart can be resized at any time, so the pixel coordinates of the text could change at any time). Thanks very much Abiel
