\title Creating Spline Charts
\brief Shows how to create a simple spline chart.
\image examples_splinechart.png {Screenshot showing a spline chart example}
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.

Now let's add some data points to the series.
\snippet chartsgallery/splinewidget.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.

Then we create a QChartView object with QChart as a parameter. This way we don't need to create
a QGraphicsView scene ourselves.
