I have not done this for a couple of years. You start an Excel automation session (you could leave visible false). The worksheet would be opened. The chart would be copied. And then something like a paste special would put it in your container.

I recordered an Excel macro to get the VBA for the chart copy. Providing we have a VFP Excel Automation running and the work sheet with the chart is the Active sheet:

oExcel.ActiveChart.ChartArea.Select
oExcel.ActiveChart.ChartArea.Copy

Then close the automation (if you need too) and paste special the contents of the clipboard to your VFP container. There are other image handling commands in VFP - you might look at those too.
