\brief Series for creating horizontal percent bar chart.
|
|
|
|
|
|
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. Bars with zero value are not drawn.
|
|
|
|
|
|
See the \l {HorizontalPercentBarChart Example} {horizontal percent bar chart example} to learn
|
|
|
how to create a horizontal percent bar chart.
