drumslave-git commented on issue #8151: dataset 可以为每个数据指定样式 URL: https://github.com/apache/incubator-echarts/issues/8151#issuecomment-530690619 Hi. If anyone needs it, I found a workaround. My dataset looks like this: ``` {source: [ {value: 15, name: 'test', color: '#FF00FF'}, ... ]} ``` Before chart init you need to add such code ``` import echarts from 'echarts'; const VISUAL_PRIORITY = echarts.PRIORITY.VISUAL.COMPONENT; echarts.registerVisual(VISUAL_PRIORITY, { createOnAllSeries: true, reset: function (seriesModel) { const data = seriesModel.getData(); data.each(function (idx) { const itemModel = data.getItemModel(idx); let color = itemModel.get('itemStyle.color'); if(!color){ // if there is no color set in normal way color = itemModel.get('color'); if(color && typeof color === 'string'){ // if there is no such field in dataset, it can return array (default color palette) data.setItemVisual(idx, 'color', color); } } }); } }); ``` After this you can init charts as always. Using such approach you can do any calculations based on your dataset item data to determine color. Don't know if it is good, but works for me and I got no other choice.
