Interface: ChartOptions
Structure describing options of the chart. Series options are to be set separately
Properties
width
• 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
• 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
• 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
• 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.
Please make sure you enable it and set an appropriate font color and size to make your watermark visible in the background of the chart. We recommend a semi-transparent color and a large font. Also note that watermark position can be aligned vertically and horizontally.
