Interface: ChartOptionsBase

Represents common chart options




width: number

Width of the chart in pixels

Default Value

If 0 (default) or none value provided, then a size of the widget will be calculated based its container's size.


height: number

Height of the chart in pixels

Default Value

If 0 (default) or none value provided, then a size of the widget will be calculated based its container's size.


autoSize: boolean

Setting this flag to true will make the chart watch the chart container's size and automatically resize the chart to fit its container whenever the size changes.

This feature requires ResizeObserver class to be available in the global scope. Note that calling code is responsible for providing a polyfill if required. If the global scope does not have ResizeObserver, a warning will appear and the flag will be ignored.

Please pay attention that autoSize option and explicit sizes options width and height don't conflict with one another. If you specify autoSize flag, then width and height options will be ignored unless ResizeObserver has failed. If it fails then the values will be used as fallback.

The flag autoSize could also be set with and unset with applyOptions function.

const chart = LightweightCharts.createChart(document.body, {
autoSize: true,


watermark: WatermarkOptions

Watermark options.

A watermark is a background label that includes a brief description of the drawn data. Any text can be added to it.
