\class QScatterSeries
|
|
|
\brief The QScatterSeries class is used for making scatter charts.
|
|
|
|
|
|
\mainclass
|
|
|
|
|
|
The scatter data is displayed as a collection of points on the chart. Each point determines the position on the horizontal axis
|
|
|
and the vertical axis.
|
|
|
|
|
|

|
|
|
|
|
|
Creating basic scatter chart is simple:
|
|
|
\code
|
|
|
QScatterSeries* series = new QScatterSeries();
|
|
|
series->append(0, 6);
|
|
|
series->append(2, 4);
|
|
|
...
|
|
|
chart->addSeries(series);
|
|
|
\endcode
|
|
|
*/

|
|
/*!
|

|
\qmlclass ScatterSeries QScatterSeries
|
|
|
\inherits XYSeries
|
|
|
|
|
|
The following QML shows how to create a chart with two simple scatter series:
