Peter,
SetSourceData AFAIK not exists in Graph Activex but Excel. Here I assume you mean ActiveX MSGraph control.
For PlotBy changing use :
THISFORM.oGrafico.object.Application.Plotby = 2 && Or one for rows

It doesn't have an ActiveSheet too but just one datasheet. To acces and change values use :
THISFORM.oGrafico.object.Application.DataSheet ie:

with THISFORM.oGrafico.object.Application.DataSheet
  * Replace C14-C24 with A1-A10 * 2 
  for ix = 10 to 20
   .Range('A5:A20').Cells(ix,3).Value = ;
   .Range('A1:B10').Cells(ix,1).Value * 2 
  endfor
  * Set B25-E35 to 100
  .Range('B25:E35').Cells.Value = 100
  * Clear values from A1-B30
  .Range('A1:B30').Cells.Clear
endwith

In the above note that if initial datasheet didn't have columns B-E that would be created and added to legend.
