There are resources trXReverse and trYReverse that generally work
for all coordinate axes and plot types except maps.

There is currently no such resource for XY plots. For contour plots
there is a
resource called sfExchangeDimensions that would do what you want
as long as 2D coordinate arrays are not used.
