6 | 6 | Charts API is build on top of Qt Graphics View Framework. Charts can be displayed as QGraphicsWidget using QChart class. However |
|
7 | 7 | there is also convenience class QChartView which is QWidget based. These lets quickly use QCharts as normal Qt widget. |
|
8 | 8 | |
|
9 | 9 | Each chart type is represented by QAbstractSeries derived class. To create given chart type users have to use instance of related series class and add it to QChart instance. |
|
10 | 10 | \code |
|
11 | 11 | QLineSeries* series = new QLineSeries(); |
|
12 | 12 | series->add(0, 6); |
|
13 | 13 | series->add(2, 4); |
|
14 | 14 | ... |
|
15 | 15 | chartView->chart()->addSeries(series); |
|
16 | chartView->chart()->createDefaultAxes(); | |
