Sounds to me like you switched your X and Y values for your contour
plot, but it is impossible to know without seeing some code.

By the way, I can't think of a reason why cgPlot would have to be used
with cgImage to set up a coordinate system. cgImage is perfectly capable
of doing this on its own.
