    v4.0.4

    2018-02-28

    [Recovery Build]

    • [^] Fixed bar layout problem. See #7831.

    v4.0.3

    2018-02-27

    v4.0.2

    2018-01-18

    • [^] Fixed that in some case the scollable legend (legend.type: 'scroll') caused ghost. See #7502.

    • [^] Fixed that the selected option did not work in the data item of pie. See #7515.

    v4.0.1

    2018-01-17

    v4.0.0

    2018-01-16

    • [+] 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.

    • [+] Supported WAI-ARIA (the Accessible Rich Internet Applications Suite） to help the disabled people to access the data visualization in web.

    • [+] Since ECharts4, the options label and itemStyle has been flattened. The original level of normal is not needed any more, which make ECharts option more neat. As always, The previous option style in ECharts3 is still be compatible.

    • [+] Added two color themes, named 'light' and 'dark'. Apply them by echarts.init(dom, themeName);.

    • [+] Supported that auto collect legend names when legend.data is not specified.

    • [+] Supported that auto collect category names when axis.type is 'category' and axis.data is not specified.

    v3.8.4

    2017-11-13
    • [^] Fixed that registerMap is null on index*.js.
    • [^] Fixed some CommonJS incorrect brought by injection.

    v3.8.2

    2017-11-10
    • [^] Fixed backward compatibility problems brounght by 3.8.0:
      • In 3.8.0, the content in lib directory is the same as the content in src directory (both are ES Module), which may not compatible with the old verisons of node and webpack. So rollback to commonJS format in lib of 3.8.2.
      • In 3.8.0, the source code in src constains 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.js manually or make some settings in webpack/rollup (Check custom build tutorial please), which is not backward compatible. So we have removed __DEV__ from the codes in echarts/lib/** in 3.8.2. If dev helper info is required, use codes in echarts/src/**.
      • After 3.8, echarts/src/echarts.js (the same as echarts/lib/echarts.js in 3.8.0) does not include util methods, which used to be mounted on it. Now util methods are listed in echarts/src/export and mounted on echarts/echarts*.js. But it is not backward compatibility, so we have rollbacked to mount them on echarts/lib/echarts.js in 3.8.2.
      • The way of including echarts/extension/dataTool, havs been rollbacked to the original approach before 3.8, where it must be included explicitly, and the namespace will be mounted on echarts namespame.
    • [^] Fixed the problem that SVG renderer throws error when encounter null value.

    v3.8,0

    2017-11-07

    • [+] Supported Tree Chart, including horizontal layout, vertical layout, radial layout.

    • [+] Supported SVG Renderer (beta), enable developers to choose SVG or Canvas renderer based on their platfroms and functional requirments.

    • [+] Source code of echarts has been switched to ES Module, which enabled tree shaking of bundle and reduced size.

    • [+] Supported build scripts for creating custom build, including multiple language support. See custom build tutorial. And added Finnish support, which is contributed by xvaara in PR #6863.

    • [+] Supported axis arrow. See #6675.

    • [+] Supported strokeWidth and strokeColor in treemap. See #6804.

    • [+] Supported show adjacent nodes in graph. See #6772.

    • [^] Fixed the area calculation when grid.containLabel is true and axis is rotated. Thanks xvaara for PR #6951.

    • [^] Fixed that the calculation of interval is not incorrect when axisLabel.rotate is set in category axis. See #4170. Thankslanyuechen for PR #6903.

    • [^] Fixed the negative problem in dataTool.prepareBoxplotData. Thanks d-rudolf for PR #6749.

    • [^] Enhanced the label interval of time axis. Thanks xiaoshan00 for PR #6808.

    • [^] Supported radiusAxis.inverse. See #6805 and #4253.

    • [^] Renamed some variables to avoid webpack special variable name. See #6788.

    • [^] Fixed position problem of scrollable legend. See #6756.

    • [^] Fixed that the themeRiver legend color is incorrect. See #6932.

    • [^] Fixed that brush empty value caused error thrown. See #6892.

    • dist/echarts/echarts.simple.js do not includ utils, which used to be mounted on echarts. dist/echarts/echarts.common.js and dist/echarts/echarts.js keep including them as before. And developers can custom build to include them.

    • Changes about dataTool: When using dist/echarts/echarts.simple.js or dist/echarts/echarts.common.js, dist/echarts/extension/dataTool.js should be manually included as before, but the namespace dataTool will not be mounted to echarts. When using dist/echarts/echarts.js, echarts.dataTool is included automatically by default.
