Legend
The Chart legend displays the name of the configured data series.
To customize the legend, use the ChartLegend configuration component.
The following example demonstrates how to configure the position and orientation of the Chart legend.
Hiding the Legend
If you set the series names, the Chart displays a default legend.
The following example demonstrates how to hide the legend by using its visible property.
Configuring the Legend Items
The Legend Item types and settings are derived from the series configuration. For additional configuration, use the series legendItem
property.
The following example shows the different Legend Item types:
Clicking Legend Items
Clicking the legend items triggers the onLegendItemClick event which can be used to toggle the visibility of the clicked series. When onLegendItemClick is not handled, the Chart itself toggles the series visibility.
Customizing the Position
You can remove the legend from the flow and absolutely position it by setting the position to custom and configuring the offsetX and offsetY options.
Setting a Title
The Chart legend section can be configured to hold a title with customizable layout and content.
To define a title, use the ChartLegendTitle component.
