New Revision: 60041

Modified:
   pypy/build/benchmem/report.py
   pypy/build/benchmem/report_graphic.py
Log:
Add pause histogram generation. Has one important problem currently: the bars are rendered over each other. Matplotlibs code does not seem to support multiple series with different lengths, so a better plotter would need to build upon bars.
