Since intensity graphs use only indexes as X and Y scales, you'll have to redefine a scale, using indexes !
The attached vi shows a way of doing it : redesigning the 2D intensity array, with an increased number of rows and columns to be able to "fake" non-uniformly spaced data.
You'll have to build a custom scale and to overlay it over the graph control, after hidding the original scale.
