Angular PieChart - Rearrange Legend Items

Although the legend's layout is virtually universal, in some cases, you may need to slightly adjust it, for example, rearrange legend items. You can learn how to do it from the following instructions.

  • Choose legend orientation
    Depending on whether the legend is oriented vertically or horizontally, the PieChart arranges legend items in columns or in rows. To change the legend orientation, use the orientation property.

    jQuery
    JavaScript
    $(function() {
    $("#pieChartContainer").dxPieChart({
        // ...
        legend: {
            orientation: "vertical" // or "horizontal"
        }
    });
});
    Angular
    HTML
    TypeScript
    <dx-pie-chart ...>
    <dxo-pie-chart-legend
        orientation="vertical"> <!-- or "horizontal" -->
    </dxo-pie-chart-legend>
</dx-pie-chart>
    import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxPieChartModule
    ],
    // ...
})
    Vue
    App.vue
    <template> 
    <DxPieChart ... >
        <DxLegend orientation="vertical"/> <!-- or "horizontal" -->
    </DxPieChart>
</template>

<script>
import DxPieChart, {
    DxLegend
} from 'devextreme-vue/pie-chart';

export default {
    components: {
        DxPieChart,
        DxLegend
    }
}
</script>
    React
    App.tsx
    import React from 'react';
import PieChart, {
    Legend
} from 'devextreme-react/pie-chart';

function App() {
    return (
        <PieChart ... >
            <Legend orientation="vertical" /> {/* or "horizontal" */}
        </PieChart>
    );
}

export default App;
    NOTE
    To center a horizontally-oriented legend, assign "center" to the horizontalAlignment property. For details on the legend's location, refer to the Relocate the Legend topic.

  • Set the number of columns or rows
    To distribute all legend items between several columns (in a vertically-oriented legend) or rows (in a horizontally-oriented legend), set the columnCount or rowCount property respectively.

    jQuery
    JavaScript
    $(function() {
    $("#pieChartContainer").dxPieChart({
        // ...
        legend: {
            // ...
            columnCount: 3
            // rowCount: 2
        }
    });
});
    Angular
    HTML
    TypeScript
    <dx-pie-chart ...>
    <dxo-pie-chart-legend ...
        [columnCount]="3">
        <!-- [rowCount]="2"> -->
    </dxo-pie-chart-legend>
</dx-pie-chart>
    import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxPieChartModule
    ],
    // ...
})
    Vue
    App.vue
    <template> 
    <DxPieChart ... >
        <DxLegend ...
            :column-count="3"
            <!-- :row-count="2" -->
        />
    </DxPieChart>
</template>

<script>
import DxPieChart, {
    DxLegend
} from 'devextreme-vue/pie-chart';

export default {
    components: {
        DxPieChart,
        DxLegend
    }
}
</script>
    React
    App.tsx
    import React from 'react';
import PieChart, {
    Legend
} from 'devextreme-react/pie-chart';

function App() {
    return (
        <PieChart ... >
            <Legend
                columnCount={3}
                /* rowCount={2} */
            />
        </PieChart>
    );
}

export default App;

  • Adjust the empty space between columns and rows
    Regardless the legend orientation, you can adjust the empty space between columns and rows using the columnItemSpacing and rowItemSpacing properties respectively.

    jQuery
    JavaScript
    $(function() {
    $("#pieChartContainer").dxPieChart({
        // ...
        legend: {
            // ...
            columnItemSpacing: 20,
            rowItemSpacing: 30
        }
    });
});
    Angular
    HTML
    TypeScript
    <dx-pie-chart ...>
    <dxo-pie-chart-legend ...
        [columnItemSpacing]="20"
        [rowItemSpacing]="30">
    </dxo-pie-chart-legend>
</dx-pie-chart>
    import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxPieChartModule
    ],
    // ...
})
    Vue
    App.vue
    <template> 
    <DxPieChart ... >
        <DxLegend ...
            :column-item-spacing="20"
            :row-item-spacing="30"
        />
    </DxPieChart>
</template>

<script>
import DxPieChart, {
    DxLegend
} from 'devextreme-vue/pie-chart';

export default {
    components: {
        DxPieChart,
        DxLegend
    }
}
</script>
    React
    App.tsx
    import React from 'react';
import PieChart, {
    Legend
} from 'devextreme-react/pie-chart';

function App() {
    return (
        <PieChart ... >
            <Legend
                columnItemSpacing={20}
                rowItemSpacing={30}
            />
        </PieChart>
    );
}

export default App;
