\title SplineChart Example
\ingroup qtcharts_examples
\brief The example shows how to create a simple spline chart.
\image examples_splinechart.png
To create spline charts we need to put our data into QSplineSeries. QSplineSeries automatically
calculates spline segment control points that are needed to properly draw the spline.
\snippet splinechart/main.cpp 1
Now let's add some data points to the series.
\snippet splinechart/main.cpp 2
The data series has been populated. To display it on a chart we create a QChart object and add
the data series to it. We also set the title and the values range on the y-axis, so that our
chart's visibility is better.
\snippet splinechart/main.cpp 3
Then we create a QChartView object with QChart as a parameter. This way we don't need to create
a QGraphicsView scene ourselves. We also set the Antialiasing on to have the rendered lines
look nicer.
\snippet splinechart/main.cpp 4
Finally, we set the QChartView as the windows's central widget.
