:-) you answered faster... I knew I shouldn't do 10 things at the same
time!
for i=0, 210 do oplot,[!X.Crange[0], !X.Crange[1]], [!Y.Crange[0] +
i*((!Y.Crange[1]-!Y.Crange[0])/210),!Y.Crange[0] +
i*((!Y.Crange[1]-!Y.Crange[0])/210)]
In the second loop, change !X for !Y, !Y for !X and 210 for 130...

You just have do do two loops of "oplot", one for all your horizontal
grid lines and the other for all the vertical grid lines.
