Is this

Using the ListDensityPlot example from the Mathematica Book, pp
159-160 I think this does what you want.
t3=Table[Mod[x,y],{y,20},{x,30}];
ListDensityPlot[Reverse[t3],FrameLabel->{None,y,x,None},
FrameTicks->{None,Table[{i, 20-i}, {i,0,20,5}], Range[0,30,5],
None}];
It is necessary to know what the coordinate ranges are so the
FrameTicks can be tailored correctly.
