Axis labels in React Chart component

3 Feb 202624 minutes to read

To get start quickly with Axis Labels in React Charts, you can check on this video:

Smart axis labels

When axis labels overlap due to limited space or dense data points, the labelIntersectAction property can be used to control how the labels are rendered. This helps improve readability by automatically adjusting label visibility or orientation.

When setting labelIntersectAction as Hide, overlapping labels are hidden to avoid visual clutter.

When setting labelIntersectAction as Rotate45, the labels are rotated by 45 degrees to reduce overlap.

When setting labelIntersectAction as Rotate90, the labels are rotated vertically to maximize space utilization.

Axis labels positioning

By default, axis labels are positioned outside the axis line. Labels can also be placed inside the axis line using the labelPosition property, which is useful when optimizing space within the chart area.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ColumnSeries, Legend, Category, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';

function App() {
    const primaryxAxis = { valueType: 'Category', labelPosition: 'Inside' };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis}>
      <Inject services={[ColumnSeries, Legend, Tooltip, DataLabel, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={categoryData} xName='country' yName='gold' type='Column'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;

Multilevel labels

Multiple levels of labels can be displayed on an axis using the multiLevelLabels property. This feature is useful for grouping related categories and improving data interpretation. The following configuration options are available:

• Categories
• Overflow
• Alignment
• Text style
• Border

Note: To use multilevel label feature, we need to injectMultiLevelLabel module into the services.

Categories

Using the categories property, the start, end, text, and maximumTextWidth values of multilevel labels can be configured to define the label range and content.

Overflow

Sorting

The chart’s data source can be sorted using the sort method of chart. The arguments that are required to pass to sort method are data of chart. The fields depend on which sorting is performed either x or y, and the isDescending with which data source values are sorted in either ascending or descending.

Edge label placement

Labels with long text at the edges of an axis may appear partially outside the chart area. To avoid this, use the edgeLabelPlacement property in the axis. This property moves the label inside the chart area or hides it for better appearance. By default, the edgeLabelPlacement property is set to Shift, ensuring that labels are repositioned inside the chart area to prevent overlap.

Trim using maximum label width

Axis labels can be trimmed when they exceed the available space using the enableTrim property. The width of the labels can also be customized using the maximumLabelWidth property. The default maximum label width value is 34.

Line break support

The line break feature is used to display long axis label text across multiple lines. In the following example, the x value in the data source contains long text, which is split into two lines using the <br> tag.

Axis label template

The axis label template allows axis labels to be customized using HTML content. This enables conditional styling and the inclusion of dynamic elements such as icons, images, or additional contextual data. This customization is enabled by setting the template content in the labelTemplate property of the AxisModel.
