Detailed Description▲
The scatter data is displayed as a collection of points on the chart. For each point, two values are specified that determine its position on the horizontal axis and the vertical axis.
The following code snippet illustrates how to create a basic scatter chart:
QScatterSeries* series = new QScatterSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);For more information, see ScatterChart Example and Scatter Interactions Example.
