I've installed Plot plug-in and it works for free-style projects fine.
But for multi-configuration project there is no "Plots" section appears in side
menu at all. However in log files i see:
========
Recording plot data
Saving plot series data from: /home/hudson/workspace/sso/label/fc6/trunk/
fixmes.cnt
...
========
so data catched and saved in csv files in workspace directory.
