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
zoomX as well. Finally, we add both
scrollbarY – controlling zooming is their default behavior, so there’s nothing extra you need to do.
