I'm looking at a job that has, in text:

"Disk Usage: Workspace 31MB, Builds 86MB"

But the graph shows a blue line (workspace) at roughly 31 mb, but the build line
is at about 9 mb which represents the last build.

So in total, this plugin is tracking three things:

1 - workspace size
2 - total build count
3 - actual build size count

Could we have another line on the graph for total builds to match the text?
