Have the current total displayed numerically somewhere as well as on the graph axis.
Right now the only way to see the total on graphs like "Do more" is to look at the axis, which for big graphs can be a little tricky to get precise numbers. It would be nice to be able to see this as a number somewhere, for things like sanity checks (and bragging rights!)
(whoops, forgot to update this! We did this – see the comment.)

See the sidebar, Goal Progress >> "NOW". You are far from the only one who misses that though! As Andy has pointed out, the natural thing to do is make it a mouseover on the current datapoint.
