Detailed Description

Charts API is built on top of Qt Graphics View Framework. Charts can be displayed as QGraphicsWidget using the QChart class. However there is also the convenience class QChartView, which is QWidget based. These enable us to quickly use Qt Charts as a normal Qt widget.

Each chart type is represented by the QAbstractSeries derived class. To create charts, the users have to use an instance of the related series class and add it to a QChart instance.

QLineSeries* series = new QLineSeries();
series->add(0, 6);
series->add(2, 4);
...
chartView->chart()->addSeries(series);
chartView->chart()->createDefaultAxes();
