Hi,

I think, there is no way to use floating point indices for the
2D-Matrix.
What I would do is to scale the x/y-coordinates.
for example: 0 is element 0,
             0.25 is element 1
             0.5 is element 2
             and so on....
you can scale the X and Y-axis of the graph with the same factor, so
that the axes are correct labeld.

I hope this helps..
