echarts实现颜色渐变的漏斗图（包括自定义各种配置项的属性）

实现效果图：

实现代码：

option = {
    color: [new echarts.graphic.LinearGradient(0, 1, 0, 0, [{
        offset: 0,
        color: '#FB8B29'
    },
    {
        offset: 1,
        color: '#ffffff'
    }]), new echarts.graphic.LinearGradient(0, 1, 0, 0, [{
        offset: 0,
        color: '#FFB547'
    },
    {
        offset: 1,
        color: '#ffffff'
    }]), new echarts.graphic.LinearGradient(0, 1, 0, 0, [{
        offset: 0,
        color: '#50FFF9'
    },
    {
        offset: 1,
        color: '#ffffff'
    }]), new echarts.graphic.LinearGradient(0, 1, 0, 0, [{
        offset: 0,
        color: '#8579FF'
    },
    {
        offset: 1,
        color: '#ffffff'
    }]), new echarts.graphic.LinearGradient(0, 1, 0, 0, [{
        offset: 0,
        color: '#2076EF'
    },
    {
        offset: 1,
        color: '#ffffff'
    }])],
