pissang commented on issue #9700: Pie chart with radial gradient URL: https://github.com/apache/incubator-echarts/issues/9700#issuecomment-452154285 It's better to use `global` coordinates to declare the radial gradient in your scene. ```js option = { "color": [ "rgb(65, 140, 240)", "rgb(252, 180, 65)", "rgb(224, 64, 10)", "rgb(5, 100, 146)", ], "dataset": [ { "source": [ { "name": "A", "value": 25, }, { "name": "B", "value": 25, }, { "name": "C", "value": 25 }, { "name": "D", "value": "25" } ], } ], "series": [ { "type": "pie", "startAngle": 0, data: [ { "name": "A", "value": 25, }, { "name": "B", "value": 25, }, { "name": "C", "value": 25 }, { "name": "D", "value": "25" } ], "itemStyle": { color: function (args) { var c = option.color[args.dataIndex], c2 = c.replace(')', ',.8)'), c3 = c.replace(')', ',.9)') return { // Use global coordinates global: true, type: 'radial', x: myChart.getWidth() / 2, // calculate x y: myChart.getHeight() / 2, // calculate y r: 200, colorStops: [ { offset: .75, color: c3 }, { offset: .95, color: c2 }, { offset: 1, color: c } ] } } }, } ] } ```
