\class QHorizontalStackedBarSeries

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