How do i overload an axis of a plot with different data range?

I'm creating plots that show the number of occurrences of divergence and vorticity values within specified ranges from a wind sensor (RapidSCAT) swath . Those are collected into a 2D array where the other dimension is local time. We are looking for diurnal differences in those observations.

When I plot the resulting array, the Y axis shows the "bin number" into which each divergence or vorticity observation has been sorted. Bin 1 collects the lowest values. Bin 64 collects the highest values. Data values in between max and min get sorted into appropriate bins between 1 and 64.

When I plot the result, I'd like the graph's Y axis to show the actual divergence or vorticity data range instead of the bin number (1-64). I do have the data range available. Is there a way to force those numbers into the Y axis labeling in substitution for the bin numbers?

Thanks!

What type of plot are you using? Some are more amenable to changing their properties than others.
