d.correlate  displays  graphically  the  results of a r.stats analysis run on two raster map layers. This
       module highlights the correlation (or lack of it) among data layers (scattergram).

       The results are displayed in the active display frame on the user’s graphics monitor. d.correlate  erases
       the  active  frame before displaying results. If no graphics monitor is open, a file map.png is generated
       in the current directory.

d.correlate  - Prints a graph of the correlation between raster maps (in pairs).

       If three or four map layers are specified, the correlation among each combination of two data  layers  is
       displayed.
