\title SplineChart Example
\subtitle
The example shows how to create simple spline chart.
\image splinechart_example
To create spline chart we need to put our data into QSplineSeries. QSplineSeries automatically calculates spline segment control points that are needed to properly draw the spline.
\snippet ../examples/splinechart/main.cpp 1
Customize the look of the spline, by setting its pen's color and pen's width
\snippet ../examples/splinechart/main.cpp 2
Now lets add some data points to the series.
\snippet ../examples/splinechart/main.cpp 3
The data series has been populated. To display it on a chart we create QChart object and add the data series to it. We also set the title and the values range on y axis, so that our chart is better visible.
\snippet ../examples/splinechart/main.cpp 4
Then we created a QChartView object with QChart as a parameter. This way we don't need to create QGraphicsView scene ourselves. We also set the Antialiasing on to have the rendered lines look nicer.
\snippet ../examples/splinechart/main.cpp 5
In the end we set the QChartView as the windows's central widget.
\snippet ../examples/splinechart/main.cpp 6
