[PATCH 2/2] tools/power/x86/intel_pstate_tracer: Use pygnuplot package for Gnuplot

[Swapnil Sapkal <swapnil.sapkal@xxxxxxx>]

In intel_pstate_tracer.py, Gnuplot is used to generate 2D plots.
In current implementation this tracer gives error while importing
the module because Gnuplot is imported from package Gnuplot-py which
does not support python 3.x. Fix this by using pygnuplot package to
import this module.
