Radial Line Graph
Radial line graph (also known as Polar line chart) is useful for displaying cyclical data of several series in a circular form.
Key implementation details
We create a
DateAxis as our X (circular) axis.
AxisRendererCircular handles its rendering.
ValueAxis is rendered by
AxisRendererRadial. Then we create
RadarLineSeries for our line graphs and set
valueYField to the respective value fields from the dataset. Finally, we add both horizontal and vertical scrollbars and they handle zooming automatically without us having to do any extra work.
