\brief Series for creating a bar chart
|
|
|
\mainclass
|
|
|
|
|
|
QAbstractBarSeries represents a series of data shown as bars. The purpose of this class is to draw bars to
|
|
|
the position defined by data. Single bar is defined by QPointF, where x value is the x-coordinate of the bar
|
|
|
and y-value is the height of the bar. The category names are ignored with this series and x-axis
|
|
|
shows the x-values.
|
|
|
|
|
|
See the \l {BarChart Example} {bar chart example} to learn how to create a simple bar chart.
