reflex-echarts

A Reflex wrapper for echarts-for-react library.

Installation

pip install reflex-echarts

Usage

See echarts_demo/echarts_demo.py for a working example.

Props are based on the echarts-for-react library, so please refer to the documentation there for further explanation.

Themes

Themes can be set by passing a theme prop to the ECharts component.

To load custom themes, provide the JS code that ultimately calls echarts.registerTheme as a string to the register_theme_code prop (this cannot be a State Var).

Limitations

• Event handling is not yet implemented.
• Inline functions for formatters and data key extraction is not implemented. Due to how the chart option is serialized as JSON, there is not a clean way to pass inline functions from the Python backend to the Javascript frontend.
• All chart types are available, which increases the bundle size of the application. There is not currently a mechanism to only include the chart types which are used.
• Cannot figure out how to load external themes from a JS file...
