Chart Intersection

I got an aplicative, which has a chart with several waveforms.

By pressing the mouse right click, a vertical cursor is shown on screen (which would be a drawLine). This cursor slides horizontally over the chart. I would like the cursor to show on screen the coordinates of its intersection with the many waveforms dinamically, as it slides over the chart. What i have so far is to make it show a single mark where the mouse is pressed.

Thanks

Joao
