Adding depths to time plot?

[rwbc]

It would be nice if you could add the depths also into the time plot.
May be with a user settable factor for scaling them to fit better into the canvas?
(e.g. in fast games with 0.x - some seconds per move, depths still could be 15 - 20
and then a lot of space would be wasted on the image.)

It would help to see anomalities with relatively low depths despite higher time used.
(Mostly user introduced problems with the tournament setup)

What do you think?
