Well, I don't know. This is how I would do an animation
of a contour plot:

cgLoadCT, 33
XInterAnimate, Set=[640, 512, 12], /Showload
FOR j=0,11 DO BEGIN
cgContour, cgDemodata(18), /Fill, Background='white', /Outline
XInterAnimate, Frame=j, Window=!D.Window
ENDFOR
XInterAnimate, 20
END

Cheers,

David
