It's very interesting, but you don't plot the significative value i.e.
the difference between single process and multi process.

Could you make this change? I'd like very much to have a single graph
with three entity (%CPU single process, %CPU multi process, difference).

Also I think that the value to get from ctx is the lower from the 5
generated (I don't know if you've used this).

To have the same graph for UP also it would be important.

Sorry... I'm too esigent ;-)
