mistercrunch opened a new pull request, #34876:
URL: https://github.com/apache/superset/pull/34876
## Summary
Implements fine-grained theming control for ECharts visualizations through
the Superset theme system. Users can now override ECharts configuration options
globally or per chart type without modifying individual chart configurations.
## Key Features
- **Global overrides**: Apply settings to all ECharts visualizations via
`echartsOptionsOverrides`
- **Chart-specific overrides**: Target specific chart types via
`echartsOptionsOverridesByChartType`
- **Smart merging**: Deep object merging with array replacement using lodash
`mergeWith`
- **Proper precedence**: Chart-specific > Global > Plugin defaults > Base
theme
## Technical Implementation
- Added theme interface properties to `SupersetTheme` with TypeScript support
- Enhanced core `Echart.tsx` component with intelligent merge logic at
single injection point
- Updated chart components to pass `vizType` for chart-specific targeting
- Implemented custom array replacement logic to ensure proper ECharts
configuration behavior
## Testing & Validation
- Comprehensive unit tests covering merge behavior and edge cases
- All pre-commit hooks passing (ESLint, TypeScript, formatting)
- Documentation updated with usage examples and best practices
## Usage Example
```javascript
// Theme configuration
{
echartsOptionsOverrides: {
grid: { left: "10%", right: "10%" },
tooltip: { backgroundColor: "rgba(0,0,0,0.8)" }
},
echartsOptionsOverridesByChartType: {
echarts_pie: { legend: { orient: "vertical" } },
echarts_timeseries: { xAxis: { axisLabel: { rotate: 45 } } }
}
}
```
This enables powerful corporate branding and custom styling capabilities
while maintaining backward compatibility.
