angleAxis(Object)

极坐标系的角度轴。

for (let i = 0; i <= 360; i++) { const t = i / 180 * Math.PI; const r = Math.sin(2 * t) * Math.cos(2 * t); data.push([r, i]); }

{{ use: partial-component-id( prefix = “#” ) }}

polarIndex(number) = 0

角度轴所在的极坐标系的索引，默认使用第一个极坐标系。

startAngle(number) = 90

起始刻度的角度，默认为 90 度，即圆心的正上方。0 度为圆心的正右方。

如下示例是 startAngle 为 45 的效果：

~400x400

clockwise(boolean) = true

刻度增长是否按顺时针，默认顺时针。

如下示例是 clockwise 为 false （逆时针）的效果：

~400x400
