ECharts 配置渐变色

径向渐变

backgroundStyle: {
  opacity: 0,
  color: {
	  type: 'radial', // 径向渐变
	  x: 0.5, // 圆心坐标（中心）
	  y: 0.5,
	  r: 1,
	  colorStops: [
		  {
			  offset: 1,
			  color: 'rgba(255, 255, 255,1)',
		  },
		  {
			  offset: 0,
			  color: 'rgba(255, 255, 255,0.1)',
		  },
	  ],
	  globalCoord: false,
  },
}

线性渐变

color: [
  {
	type: 'linear',
	x: 0,
	y: 0,
	x2: 0,
	y2: 1,
	colorStops: [
	  {
		offset: 1,
		color: '#0d47e1', //下
	  },
	  {
		offset: 0,
