|
13 | 13 | QChart is a QGraphicsWidget that you can show in a QGraphicsScene. It manages the graphical |
|
14 | 14 | representation of different types of QChartSeries and other chart related objects like |
|
15 | 15 | QChartAxis and QChartLegend. If you simply want to show a chart in a layout, you can use the |
|
16 | 16 | convenience class QChartView instead of QChart. |
