Chaithanya5gif opened a new pull request, #21609:
URL: https://github.com/apache/echarts/pull/21609
### What problem does this feature solve?
Currently, developers building financial/candlestick charts must rely on
external JS libraries to calculate technical indicators before passing them to
ECharts. This PR introduces a native `echarts:indicator` transform that
computes these mathematically in the data pipeline, significantly reducing
boilerplate and external dependencies.
### What does the proposed API look like?
The new transform hooks seamlessly into the existing `ExternalDataTransform`
interface:
```javascript
dataset: [{
source: stockData
}, {
transform: {
type: 'echarts:indicator',
config: {
indicator: 'macd', // Supports: 'sma', 'ema', 'macd', 'bollinger'
shortPeriod: 12,
longPeriod: 26,
signalPeriod: 9,
sourceDimension: 'Close'
}
}
}]
