Description
A TTChartOnClickSeries event occurs whenever the user clicks onto any Chart Series point. The SeriesIndex parameter is the corresponding clicked Series component, and the ValueIndex parameter refers to the exact clicked point in the Series. The Button, Shift, X and Y parameters determine the mouse button and mouse cursor coordinates at the time the Series point was clicked.

WARNING:

Use the StopMouse property to control how the mouse button behaves with dual modes (scroll or zoom after a ClickOnSeries event)
