Thank you Ethan,

the file I am using is not an image is a file containing
x y z1
x+dx y z2
...

x y+dy z11
x+dx y+dy z12
...

coordinates as a 3D histogram
that I was plotting with splot as pm3d map
Using the plot "with image" it works exactly as before
however the z-color mapped value now is not starting from
the x,y (lower-left) coordinate but from x-dx/2,y-dy/2
so it is centred around x,y
