The best option is to use RRDtool.  If you can't/won't do so, you can graph
three different values (including %idle) in MRTG by shifting one value
on the Y-axis:

Let the total graph be 100%, graph %usr using the area. Graph
%usr+%sys+%wio using the line.  You will end up with a graph that
looks as if there are three different areas: %usr, (%sys+%wio) on top of
the user time and finally %idle on top of the other two.
The legend should show %usr and %(not-idle)
