Hi ,
  I am trying to draw Time Series in a window. I am using the
mm_anisotropic Mapping Mode as follows

setMapMode(PaintDC, mm_anisotropic)
SetWindowExt(PaintDC, 512, 256)   { 512 points in a window }
SetViewportExt(PaintDC, r.right, -r.bottom);  { Client area }
SetViewportOrg(PaintDC, 0,r.bottom);
draw;

The problem is if I then scrolll the window, the picture will not be
redrawn properly. 

Does anybody know what's wrong?

Lee
