This two missing properties can't be get by `getItemVisual`, so dash style will be not working in some cases like `lines`, refer to [chart/helper/Line.ts#L206](https://github.com/apache/incubator-echarts/blob/next/src/chart/helper/Line.ts#L206). It's different from [line series](https://github.com/apache/incubator-echarts/blob/next/src/chart/line/LineView.ts#L543) and [4.x](https://github.com/apache/incubator-echarts/blob/master/src/chart/helper/Line.js#L374) which are using `lineStyleModel.getLineStyle()` So how should I do to make it work for those series dependent on `chart/helper/Line.js`? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
