slight help required for #51656

Hi,

I am trying to hack on https://bugs.freedesktop.org/show_bug.cgi?id=51656 and
so far had been able to discover out the culprit to be : 'aScales' here:
http://opengrok.libreoffice.org/xref/core/chart2/source/view/charttypes/VSeriesPlottear.cxx#1001,
since aScales[0] assumes different values for different form of graphs.

It also seems to me that core/chart2/source/view/main/ChartView.cxx plays a
good role herein [to decide the location of origin on X-axis].

I am trying hard to understand and connect links between different codes
using the code pointers, but somehow am not able to take another productive
step ahead, just seem to be beating around the bush and would be glad to be
slightly motivated by small hint/clue.

Thanking you in anticipation

Regards
Prashant
