I need to get the index of the position of a cursor at an unknown x or y value. I can get the rest and I seen a GetCursorValueIndex function with the Series Heirarchy and tried it but it didnt return what I needed.
Any ideas?
Thanks,
Tom

Hi Tom,
What about doing something as I suggested
here in TCursorTool's OnChange event? OnChange's ValueIndex parameter only has valid values when the cursor is set to snap.

Yeah I used this code below for the on change event in the cursor:
Code: Select all
curpos: Integer;
curpos := Chart1.Series[seriesidx].XValues.Locate(XValue);
That works good so far. I just have to reset it to 0 if they go past the lastindex point.
Thanks,
Tom
