Is there a way to get the value of x in the chart x axis from the
values of x reported in the mousedown event?

Thanks,

Jennifer

Hi Jennifer,

yes, you can see a similar example (which does the same but using the OnMouseMove event) in the steema.public.attachments newsgroup (at news://www.berneda.com ), with the Subject : "RE: Click Chart to get Series Value (Matt)".

We have been all over the berneda newsgroups and we cannot find this-
Is there a fuinction call that will give us the x position in "chart units"
from the mouse x position. we can certsainly take it form there.

Thanks,

Jennifer

Hi, Jennifer.

Yes, sure. Use TChartSeries.XScreenToValue method or TChartAxis.CalcPosPoint method.
