Please look more carefully at the example I pointed to.
It does exactly that, using the modifiers
   origin=(60,0) dx=0.5 dy=1.5 
to re-map the coordinates of the array as it is read in.

The tick labels are not really relevant to this.
You can label the ticks however you like, automatically or
manually.
