# Overrides

The Overrides API allows you to customize elements on the chart like panes, scales, series, drawings, indicators, legends, and more.

## Chart and drawings

To override a property that relates to the chart, drawing, or trading element, you should specify this property in the [`overrides`](../../api/interfaces/Charting_Library.ChartingLibraryWidgetOptions.md#overrides) parameter of [Widget Constructor](https://charting-library-docs.xstaging.tv/latest/configuration/Widget-Constructor.md). The code sample below changes the chart background color and chart style using [`paneProperties.background`](../../api/interfaces/Charting_Library.ChartPropertiesOverrides.md#panepropertiesbackground) and [`mainSeriesProperties.style`](../../api/interfaces/Charting_Library.ChartPropertiesOverrides.md#mainseriespropertiesstyle).

```js
var widget = window.tvWidget = new TradingView.widget({
    // ...
    overrides: {
        "paneProperties.background": "#020024",
        "mainSeriesProperties.style": 2,
    }
});
```

If you want to change a property's value on the fly, you can use the [`applyOverrides`](../../api/interfaces/Charting_Library.IChartingLibraryWidget.md#applyoverrides) method.

```js
widget.applyOverrides({ "mainSeriesProperties.visible": false });
```

For specific charts in a [multiple-chart layout], use the `applyOverrides` method from the [`IChartWidgetApi`]:

```js
widget.chart(0).applyOverrides({ "mainSeriesProperties.visible": false });
```
