Try using r.stats (inputing both maps) to get a text file output of the
matching values from both maps. Then feed this into something that will make
your graphs (stat program, spreadsheet, etc.).

Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowedHi Folks,
I'm new to GRASS, and I'm hoping somebody can give me some advice to
get me started...I have two netcdf raster grids. One is seafloor age, the other is
seafloor depth. The files both cover the same geographic area,
although the grids are different resolutions.What I want to do is plot a simple x-y graph of seafloor age vs.
depth, where each point in my graph represents the a seafloor age
grid cell and the intersecting seafloor depth cell.Can this be done? Can anyone suggest some basic steps to get me
started? No instruction is too basic for me -- this is my first day
with GRASS. I have just installed GRASS (and R, just in case it's
necessary), but otherwise I have no idea how to proceed.Thanks,
Brock
