legend.type: 'scroll') caused ghost. See #7502.
[+] Supported to render up to tens millions of data directly. ECharts4 has upgrade to stream architecture, and along with detailed optimization, it has supported to render incrementally loaded data and support progressive rendering.
- Ten millions of GIS data probably take up to about hundreds MB of space. In this case chunked data loading or WebStock is required for the purpose of display graphics as soon as possible and not blocking the browser while processing loaded data. The samples of incremental data loading can be checked here: scatterGL-gps and linesGL-ny, who use ECharts GL, and lines-ny, who only uses ECharts.
- Supported the human interactions in the big data scenario, where continuous interactions (e.g., roam in geo and cartesian) will not block the browser. Benefit from the using of GPU and avoiding of layout recalculation, ECharts GL provides smooth interactions, which has been demonstrated in the examples above. Without WebGL, the basic ECharts implements progressive rendering to support non-blocking interaction, which can be checked at the pan and zoom in lines-airline and scatter-large.
[+] Published ZRender SVG Rendering Engine as an alternative backend of ECharts besides the existing Canvas Rendering Engine. The choice of rendering engine usually depends on the scenario, for example, benefit from the low memory cost, SVG Rendering Engine is suitable for mobile device, or the case that many ECharts instances exists in a single page, while the Canvas Rendering Engine is suitable for big data rendering or when visual effects required. Canvas Rendering Engine is default rendering engine. See zrender.
[+] Published Sunburst Chart to visualize hierarchical data efficiently with excellent interactions. See [examples] and (excellent) and docs.
[+] Published dataset component to support data based configuration, visual encoding and data sharing in different series.

3.8.0, the source code in
srcconstains global variable
__DEV__(which prints dev helper info for echarts users). To get the declaration of the global variable, users should include
echarts/src/config.jsmanually or make some settings in
rollup(Check custom build tutorial please), which is not backward compatible. So we have removed
__DEV__from the codes in
3.8.2. If dev helper info is required, use codes in
echarts/src/echarts.js(the same as
3.8.0) does not include util methods, which used to be mounted on it. Now util methods are listed in

textStyleexist in echarts option everywhere, for example, series-bar.label.normal.textStyle, xAxis.axisLabel.textStyle. It seems that some of them are to deep and verbose. So we removed the level of
textStyleto flatten them. That is, previous
axisLabel.textStyle.fontSizeis modified to
v3.7. Of course, the previous style is compatible all the same. Those options are flattened:
