    \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.

    \snippet chartsgallery/splinewidget.cpp 1

    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.

    \snippet chartsgallery/splinewidget.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.
