I'm not sure what you are asking for, since you didn't provide the full
script or a sample image.

Please be more specific about what kind of plot you are trying to create:
for example, do you want to draw filled contours of both datasets on the
same plot, but each with its own set of colors and levels?    How are
creating the contour plot(s)?  You only included the resource settings.

Also, what do you mean by "low(-ve)" and "high(+ve)" values?  Your said
your values start at 0, so I'm assuming you don't have any negative values.
