I have an RCP application that uses the BIRT chart engine to display an area chart. I would like to simulate a zoom capability by allowing the user to click inside the chart and use the x-axis (time) value at the mouse click point to reset the x-axis range and then regenerate/display the chart. The user would click once to select the start point and click again to select the end point.

The problem is that I can only obtain values for actual area series data points. Ideally, I would like the user to be able to click anywhere inside the chart and be able to obtain the x-axis value for that mouse click point. I could also settle for being able to click on the actual x-series value or x-series marker lines, but whenever I add a mouse click trigger to the x-series or marker line, the callback method never gets called.

Any help would be greatly appreciated.
