[OE-core] [PATCH V2 03/11] pybootchartgui/draw.py: fix drawing of samples not starting at zero

[Patrick Ohly]

The code did not handle x scaling correctly when drawing starts at
some time larger than zero, i.e. it worked for normal bootchart data,
but not for the system statistics recorded by buildstats.bbclass.
