    \title Using Polar Charts with QML
    \brief Shows how to make a few different polar chart in your QML application.
    \include qmlchartsgallery.qdocinc

    We begin with a chart that has a spline series and a scatter series with random
    data. Both series use the same axes.

           data series, one being a blue spline chart and the other being a scatter
           chart with green dots}

    The next chart shows some accurate historical data for which we need
    to use a DateTimeAxis and a AreaSeries.

           accurate historical data as an area chart with a DateTimeAxis}

    The next chart uses a CategoryAxis to make the data easier to understand.

    \image examples_qmlpolarchart3.png {Screenshot showing a polar chart with the
           axis being categorised by critical, low, normal, high, and extremely high}
