Mmmm, RSMD compared to what?  Frame 1?

You can't get such a plot right now, but what you can do is open your  
trajectory and also open a PDB file with whatever structure you want  
to measure RMSD with, and in the "Define script..." dialog put:

echo <FRAME>
match #0<+atom spec you wanted compared> #1<+atom spec you want  
compared>

Then if you play through the trajectory, in the reply log will be  
pairs of lines like this:

23
1.264

which is the frame number and the RMSD.
