Overview

Each series point can be accompanied with a label that displays the point's value(s) or custom data.

DevExtreme HTML5 JavaScript Charts SeriesPoints

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: {
            stackedline: { // or any other series type
                label: {
                    // Settings for all point labels belonging to Stacked Line series
                }
            },
            label: {
                // Settings for all point labels in the Chart
            }
        }
    });
});
Angular
HTML
<dx-chart ... >
    <dxi-series>
        <dxo-label ... >
            <!-- Settings for all point labels of an individual series -->
        </dxo-label>
    </dxi-series>
    <dxo-common-series-settings ... >
        <dxo-stackedline> <!-- or any other series type -->
            <dxo-label ... >
                <!-- Settings for all point labels belonging to Stacked Line series -->
            </dxo-label>
        </dxo-stackedline>
        <dxo-label ... >
            <!-- Settings for all point labels in the Chart -->
        </dxo-label>
    </dxo-common-series-settings>
</dx-chart>

Point labels are not visible by default. To make them visible, assign true to the label | visible option. 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 option.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        series: {
            label: {
                visible: true,
                connector: {
                    visible: true
                }
            }
        }
    });
});
Angular
HTML
<dx-chart ... >
    <dxi-series>
        <dxo-label [visible]="true">
            <dxo-connector [visible]="true"></dxo-connector>
        </dxo-label>
    </dxi-series>
</dx-chart>
