JavaScript/jQuery Chart - Resolve Overlapping
In multi-series charts, point labels often overlap. To decide how to resolve overlapping, employ the resolveLabelOverlapping property. It allows you to hide certain labels, or arrange all labels in stacks, or keep the labels as they are (i.e. overlapping).
jQuery
JavaScript
$(function() {
$("#chartContainer").dxChart({
// ...
resolveLabelOverlapping: 'stack' // or 'hide' | 'none'
});
});Angular
HTML
TypeScript
<dx-chart
resolveLabelOverlapping="stack"> <!-- or 'hide' | 'none' -->
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxChartModule
],
// ...
})Vue
App.vue
<template>
<DxChart
resolve-label-overlapping="stack"> <!-- or 'hide' | 'none' -->
</DxChart>
</template>
<script>
import DxChart from 'devextreme-vue/chart';
export default {
components: {
DxChart
}
}
</script>React
App.js
import React from 'react';
import Chart from 'devextreme-react/chart';
class App extends React.Component {
render() {
return (
<Chart resolveLabelOverlapping="stack"> {/* or 'hide' | 'none' */}
</Chart>
);
}
}
export default App;Another way to deal with overlapping labels is to hide all labels of a specific series once their count exceeds a certain limit. Mostly, this feature is useful if the series accepts new points at runtime. To specify the limit on point labels, assign a number to the maxLabelCount property.
jQuery
JavaScript
$(function() {
$("#chartContainer").dxChart({
// ...
series: [{
// ...
maxLabelCount: 10
}, {
// ...
}]
});
});Angular
HTML
TypeScript
<dx-chart ... >
<dxi-series [maxLabelCount]="10" ... ></dxi-series>
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxChartModule
],
// ...
})Vue
App.vue
<template>
<DxChart ... >
<DxSeries
:max-label-count="10"
...
/>
</DxChart>
</template>
<script>
import DxChart, {
DxSeries
} from 'devextreme-vue/chart';
export default {
components: {
DxChart,
DxSeries
}
}
</script>React
App.js
import React from 'react';
import Chart, {
Series
} from 'devextreme-react/chart';
class App extends React.Component {
render() {
return (
<Chart ... >
<Series
maxLabelCount={10}
...
/>
</Chart>
);
}
}
export default App;See Also
