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 valueXField
to date
and 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.
