What Delphi variables would I pass to Windows' ScrollDC if I wanted to use it in a TGraphicControl.  I would like to make a trend line.

The function is defined like this in Windows.pas

function ScrollDC(DC: HDC; DX, DY: Integer; var Scroll, Clip: TRect; Rgn: HRGN;
  Update: PRect): BOOL; stdcall;

DC = TGraphicsControl.Canvas.Handle

Scroll and Clip is for You to define. Rgn and Update can be set to nil. Hope this helps.

The TGraphicsControl don't published Canvas so you must do this inside component or use other component.
