M means the grids match

O means the grids are offset

S means the grids could match by sampling

D means the grids differ

Grid Comparisons

When you have multiple variables active, a table of grid comparisons appears to the right. These comparisons are between the last variable and all the others (so the last row always has matches or blanks).
