Displaying marks for individual points

Users often ask to be able to see the mark for a point just by moving the mouse over it, like you can do in Excel. There doesn't seem to be a mechanism for this with TChart. You can only switch all marks on and off using a series' 'Marks.Visible' property. Also, as there's no OnMouseMove event for a TPointerSeries, it seems that you can't retrieve any information without clicking the pointer. Or am I missing something?

Thanks for any help.

Hi.

I think the TMarksTipTool tool more less does exactly what you described above. There is an example if this tool available in TeeChart demo. Check all nodes under the "All Features -> Tools -> Mark tips" node in TeeChart demo.
