Drawing Overrides
The Overrides API includes properties that can be used to customize drawing parameters such as colors, width, size, and more. This article describes ways to customize drawings and contains a list of overrides for each drawing.
Customize drawings
This section describes ways to customize drawings.
Specify default properties
You should use the overrides
property of the Widget Constructor to specify the drawing's default properties.
For example, the following code sample specifies that all Horizontal Lines should be green and dashed.
var widget = window.tvWidget = new TradingView.widget({
// ...
overrides: {
"linetoolhorzline.linecolor": "rgba(48, 164, 22, 0.8)",
"linetoolhorzline.linestyle": 2,
}
});
Change default properties on the fly
To change the drawing's default properties after the chart is initialized, use the applyOverrides
method.
All drawings created after the applyOverrides
call have new properties. For example, the following code sample specifies that all newly created Horizontal Lines should be purple.
widget.applyOverrides({ "linetoolhorzline.linecolor": "#7f11e0" });
Change the existing drawing
If you want to change a drawing that is already on the chart, use the setProperties
method in ILineDataSourceApi
. For example, the code sample below specifies new properties for the existing Icon.
const iconId = widget.activeChart().getAllShapes().find(x => x.name === "icon").id;
const icon = widget.activeChart().getShapeById(iconId);
icon.setProperties({ size: 60, color: "#7f11e0" });
Customize a single drawing
If you need to change a style of only one drawing, create the drawing using the Drawings API and pass overrides properties as a parameter. These properties are applied above the default ones that are specified in overrides
.
For example, the code sample below specifies that the default Horizontal Line color is green and creates one red Horizontal Line.
var widget = window.tvWidget = new TradingView.widget({
// ...
overrides: {
"linetoolhorzline.linecolor": "rgba(48, 164, 22, 0.8)",
}
});
widget.onChartReady(() => {
widget.chart().createShape(
{ price: 180 },
{
shape: "horizontal_line",
overrides: { linecolor: "#FF0000" },
}
)
});
