@RavalikaP It's similar to the above.
```js
const legendModel = chart.getModel().getComponent('legend');
const legendView = chart.getViewOfComponentModel(legendModel);
const legendRect = legendView.group.getBoundingRect();
const [x, y] = legendView.group.transformCoordToGlobal(legendRect.x, legendRect.y);
const { width, height } = legendRect;
console.log(x, y, width, height);
```

There are no such APIs but you can get this information `option.grid` and ` option.legend` from your input option.

@Ovilia but on option.legend and option.grid we are not getting the updated values. If it is updated then it will be easy to get it.

You may get such information via some internal APIs. Just FYI.
**Grid**
```js
// if there are multiple grids, use `getComponent('grid', gridIndex)`
const gridRect = chart.getModel().getComponent('grid').coordinateSystem.getRect();
```
**Axis**
```js
// if there are multiple axes, use `getComponent('xAxis', axisIndex)`
const xAxisModel = chart.getModel().getComponent('xAxis');
const xAxisView = chart.getViewOfComponentModel(xAxisModel);
const xAxisRect = xAxisView.group.getBoundingRect();
```
