\brief Series for creating bar chart.

\mainclass

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