JavaScript/jQuery Chart - Overview
Each series point can be accompanied with a label that displays the point's value(s) or custom data.
To configure point labels, use the fields of the label object. This object can be declared as follows.
jQuery
JavaScript
$(function() {
$("#chartContainer").dxChart({
// ...
series: [{
label: {
// Settings for all point labels of an individual series
}
}, {
// ...
}],
commonSeriesSettings: {
label: {
// Settings for all point labels in the Chart
}
}
});
});Angular
HTML
TypeScript
<dx-chart ... >
<dxi-series>
<dxo-label ... >
<!-- Settings for all point labels of an individual series -->
</dxo-label>
</dxi-series>
<dxo-common-series-settings ... >
<dxo-label ... >
<!-- Settings for all point labels in the Chart -->
</dxo-label>
</dxo-common-series-settings>
</dx-chart>

DxSeries,

DxLabel
} from 'devextreme-vue/chart';

DxChart,

return (

{/* Settings for all point labels of an individual series */}
</Label>
</Series>
<CommonSeriesSettings ... >
<Label ... >
{/* Settings for all point labels in the Chart */}
</Label>
</CommonSeriesSettings>
</Chart>
);
}
}
export default App;Point labels are not visible by default. To make them visible, assign true to the label.visible property. With this configuration, point labels are displayed detached from their respective series points. You can make the connection between labels and points more evident by making label connectors visible. For this purpose, assign true to the label.connector.visible property.

$("#chartContainer").dxChart({
// ...

label: {
visible: true,

visible: true
}
