        [
            {

        ]);
    ]
],

linear

// 线性渐变,前四个参数分别是 x0, y0, x2, y2, 范围从 0 - 1,相当于在图形包围盒中的百分比,如果 globalCoord 为 `true`,则该四个值是绝对的像素位置

    type: 'linear',
    x: 0,
    y: 0,

    y2: 1,

        offset: 0, color: 'red' // 0% 处的颜色
    }, {

}

RadialGradient

    offset: 0,
    color: '#f7f8fa'
}, {
    offset: 1,
    color: '#cdd0d5'
}]),

radial

// 径向渐变,前三个参数分别是圆心 x, y 和半径,取值同线性渐变
color: {
    type: 'radial',
    x: 0.5,
    y: 0.5,
