How to get the first and last data index in chart?

Hi, after zooming in the display, I would like to get the first and last data index shown in the chart. Would anyone please tell me how to do it with sample codes? Thanks.

Hi David,

Once you have the chart drawn, you can get the first and last indexes drawn in a series with:

Code: Select all

TChart1.Series(0).FirstValueIndex
TChart1.Series(0).LastValueIndex
