Variable-Radius Radar

amCharts Radar Chart doesn’t necessarily have to be a perfect circle. It can be anything from full circle to half-arc to a totally flat bar/line chart. Try moving the slider under the chart to change the shape.

Key implementation details

When slider position changes we simply adjust the charts startAngle and endAngle properties. We also set the axisAngle property on the Y axis renderer.
