请问Echarts中如何使用贝塞尔曲线接口?

能否提供一个基础的绘制三阶贝塞尔曲线的用例?

官网和github中没有找到相关的用例,不知道如何上手.
自行测试了下,显示不出有效的图形,基本是一片空白.

不胜感谢

没有那么麻烦吧,官方文档的实例中可以测试:

option = {
    graphic: [{
                type: 'bezierCurve',
                z: 100,
                left: 'center',
                top: 'center',
                shape: {
                    x1:0,
                    y1:0,
                    x2:300,
                    y2:300,
                    cpx1:133,
                    cpx2:266,
                    cpy1:33,
                    cpy2:-56
                }
            }
    ]
}
