\brief Series for creating grouped bar chart

\mainclass

|
|
|
|
|
QGroupedBarSeries 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. QGroupedBarSeries groups the data
|
|
|
from sets to categories, which are defined by a QStringList.
|
|
|
|
|
|
See the \l {GroupedbarChart Example} {grouped bar chart example} to learn how to create a grouped bar chart.
