"Theme" is an abstract style of ECharts charts, used to unify the styles of multiple charts. Using Online Build Tool, you can intuitively generate the theme Config file and use customized theme styles in ECharts.
You can still use setOption to override or set the theme style.
ECharts officially provides theme: default、infographic、shine、roma、macarons、vintage, etc.. Available for download here.
Import & Export
In order to facilitate secondary modification, our theme building tool supports importing and exporting Config items. The exported JSON file can be used only in this tool, but not in ECharts directly.
