\class QHorizontalPercentBarSeries | ||||
\brief Series for creating horizontal percent bar chart | ||||
\mainclass | ||||
QHorizontalPercentBarSeries 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. QHorizontalPercentBarSeries groups the data | ||||
from sets to categories, which are defined by a QStringList. | ||||
See the \l {HorizontalPercentBarChart Example} {horizontal percent bar chart example} to learn how to create a horizontal percent bar chart. | ||||
