    v5.0.0

    2020-12-03
    • Migrate codebase to TypeScript:
      • The entire code base have been migrated to TypeScript.
      • Provide DTS for the upper TS based applications, where the TS version supported is down to 3.5.
      • See more details in #13563
    • [Feature] States enhancement:
      • Support state transition animation, which brings better interaction effect when highlighting or downplaying some part of the chart.
      • Besides the state "emphasis" we already have, v5.0 provides two more configurable state: "select" and "blur" in all series. The option of them are the same as the existing "emphasis". "blur" is used the elements need to fade out when focusing some other elements. "select" is used when the element is selected by mouse/touch click or API triggering.
      • Support to blur other graphic elements when highlighting specified data through mouseover or hover linking. See examples bar-label-rotation, bar-polar-stack, bar-stack, area-stack, dataset-link, scatter-weight, tree-basic.
      • Unify the previous different state configurations in series, like highlightPolicy, focusNodeAdjacency, hoverOffset, by the option focus, blurScope and scale. See examples sankey-energy, graph, sunburst-drink.
      • See more details in #12925 and #12911.
    • [Feature] Provide a more powerful label support:
      • Use some strategies to bring better displayed labels, including:
        • Smarter text color strategy to make labels more easy to be distinguished from different background.
        • Smarter label layout in pie chart, especially when there are too many labels or insufficient space. And related issue: #6050.
        • Provide more overflow configurations.
      • Provide option set labelLayout to enable more abilities for developers to tweak the layout of the labels after it's originally positioned by the chart itself. With the options in labelLayout, developers can:
      • Support labelLine for all series, which is very useful for guiding element to related labels when labels have to be far away from the elements. See examples scatter-label-align-right, scatter-label-align-top. Related issues: #11534, #12971.
      • Support series.endLabel in line series. Label can be displayed at the end of a line.
      • Support label text animation, that is, the transition animation on text when the number text changed. Can be enabled by series.label.valueAnimation, series.endLabel.valueAnimation. See more details in #13246 and #13045.
      • See other details in #12911.
    • [Feature] Support bar realtime sorting by series.realtimeSort. See examples bar-race, and see more details in the original pull request #12484.
    • [Feature] Support data transform plug-in:
    • [Feature] Provide more smarter time axis label and tick arrangement:
    • [Feature] Support decal:
      • Decal provides a new visual type that does not only augment aria scenarios but also enrich visual effects.
      • See more details in #13304.
    • [Feature] Support transition animation in custom series.
    • [Feature] Provide a more powerful gauge:
    • [Feature] The default theme and interaction have been greatly enhanced. Some new options are provided for the style and interaction configuration:
      • Tooltip style enhancement: #12947, #13398, #13242.
      • Provide configurable dash style: #12961.
      • Axis style enhancement: #13046.

      • Enhance resize & dataZoom animation: #12965
      • Change the closing direction of a single bar, #12543.
      • Enhance pie chart animation #12553.
      • Other component style enhancement: #13008, #13013.
    • [Feature] Make i18n registerable and change the product.

      • [Feature] Sankey supports lineStyle: {color: 'gradient'}.
      • [Feature] markPoint.data.type and markArea.data.type support the value 'median'.

      • [Enhancement] Pause requestAnimationFrame when rendering finished.
      • [Fix] Fix bmap first layout may be incorrect if container's layout is flex or grid. #13432.
      • [Fix] Hide tooltip when mouse leaves the chart #13382.

      • [Fix] Skip rendering for data out of axis content in heatmap. #12991.
    • [Break] Breaking changes against v4.9:
      • The default theme colors has been changed. If intending to use the theme of v4.9-, please set option.color = ['#c23531', '#2f4554', '#61a0a8', '#d48265', '#91c7ae', '#749f83', '#ca8622', '#bda29a', '#6e7074', '#546570', '#c4ccd3'];.
      • Remove built-in map geoJSON. #13565.
      • Drop the support of the legacy IE8. The previous VML renderer (necessary in IE8) will not be updated to work in v5.0.
      • The exported modules from 'echarts/lib/export.js' is not mounted to 'echarts/lib/echarts.js' by default. If the upper application previously used import * as echarts from 'echarts/lib/echarts' and used any of the exported modules in 'echarts/lib/export.js', please change the import code to import echarts from 'echarts/index.blank', where the modules from 'echarts/lib/export.js' are mounted by default.
      • If the upper application previously imported src/echarts.js, src/chart/*.js and src/component/*.js, it can not work any more because all of the files in /src folder are migrated to *.ts.
      • The priority of the visuals between visualMap and itemStyle|lineStyle|areaStyle are reversed. That is, previously, the visuals (i.e., color, symbol, symbolSize, ...) that generated by the component visualMap has highest priority, which will overwrite the same visuals specified in itemStyle|lineStyle|areaStyle. That brought trouble to specify specific style to some certain data items. Since v5.0, the visuals specified in itemStyle|lineStyle|areaStyle has highest priority.
      • The behavior of rich.?.padding are changed. Previously rich.?.padding: [11, 22, 33, 44] indicates that padding-top is 33 and padding-bottom is 11, which is a buggy implementation because it is different from what CSS did. Since v5.0, we fix it: rich.?.padding: [11, 22, 33, 44] indicates padding-top is 11 and padding-bottom is 33.
      • aria is not included in dist/echarts.simple(.min).js since v5.0. But it is still included in dist/echarts.common(.min).js and dist/echarts(.min).js.
    • [Deprecated] Deprecated usages since v5.0:
      • Transform related props of a graphic element are changed:
        • Changes:
          • position: [number, number] are changed to x: number/y: number.
          • scale: [number, number] are changed to scaleX: number/scaleY: number.
          • origin: [number, number] are changed to originX: number/originY: number.

          • In custom series: the declarations of each element in the return of renderItem.
          • Directly use zrender graphic elements.
      • Text related props on graphic elements are changed:
        • Changes:
          • The declaration of attached text (or say, rect text) are changed.
            • Prop style.text are deprecated in elements except Text. Instead, Prop set textContent and textConfig are provided to support more powerful capabilities.

            • textShadowBlur
            • textShadowOffsetX
            • textShadowOffsetY
        • It effects these places:
          • In the graphic components: the declarations of each element. [compat, but not accurately the same in some complicated cases.]
          • In custom series: the declarations of each element in the return of renderItem. [compat, but not accurately the same in some complicated cases].
          • Directly use zrender API to create graphic elements. [No compat, breaking change].
      • API on chart instance:

    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.

    • [^] 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.

    • [^] 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.
