Zoomable Radar

This demo shows all the ways to enable zooming in a radar chart.

Key implementation details

First of all, we enable zooming with a mouse wheel right when we create the chart by setting wheelY: "zoomX". This way rotating mouse wheel zooms across the chart’s X axis (the circular one). Then we add a cursor and set its behavior to zoomX as well. Finally, we add both scrollbarX and scrollbarY – controlling zooming is their default behavior, so there’s nothing extra you need to do.
