Angular Chart - Show and Hide a Series

The Chart provides an API for showing and hiding a series at runtime. The most common use-case for this API is to show or hide a series when a user clicks the chart legend. To implement this scenario, you need to handle the legendClick event in the following manner. The isVisible(), hide() and show() are methods of the Series object.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        onLegendClick: function (e) {
            var series = e.target;
            if (series.isVisible()) {
                series.hide();
            } else {
                series.show();
            }
        }
    });
});
Angular

<dx-chart
    (onLegendClick)="legendClickHandler($event)">
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    legendClickHandler (e) {
        const series = e.target;
        if (series.isVisible()) {
            series.hide();
        } else {
            series.show();
        }
    };
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})
Vue
App.vue
<template> 
    <DxChart
        @legend-click="legendClickHandler($event)"
        ... >
    </DxChart>
</template>

<script>
import DxChart from 'devextreme-vue/chart';

export default {
    components: {
        DxChart
    },
    methods: {
        legendClickHandler(e) {
            const series = e.target;
            if (series.isVisible()) {
                series.hide();
            } else {
                series.show();
            }
        }
    }
}
</script>
React
App.js
import React from 'react';
import Chart from 'devextreme-react/chart';

class App extends React.Component {
    render() {
        return (
            <Chart
                onLegendClick={this.legendClickHandler}
                ... >
            </Chart>
        );
    }

    legendClickHandler(e) {
        const series = e.target;
        if (series.isVisible()) {
            series.hide();
        } else {
            series.show();
        }
    }
}

export default App;

A series can be hidden initially. For this, assign false to the visible property of the object that configures the series.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        series: [{
            // ...
            visible: false
        }, {
            // ...
        }]
    });
});
