Add possibility to set reverse values to axes...
Add possibility to set reverse values to axes Added support for reverse axis. This works with line, spline, scatter and area series with cartesian chart. QBarCategoryAxis is not supported, nor different bar series. Change-Id: I60f21372ea9cee7b49918d7d99de24671bdc42c3 Reviewed-by: Miikka Heikkinen <miikka.heikkinen@theqtcompany.com>

\brief Series for creating horizontal bar chart.
\mainclass
QHorizontalBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars
as groups, where bars in same category are grouped next to each other. QHorizontalBarSeries groups the data
from sets to categories, which are defined by a QStringList.
See the \l {HorizontalBarChart Example} {horizontal bar chart example} to learn how to create a horizontal bar chart.
