Internationalization in React Chart component

3 Feb 20267 minutes to read

Chart provides support for internationalization for the following elements:

  • Data label
  • Axis label
  • Tooltip

For more information about number and date formatting, see the internationalization guide: internationalization.

Globalization

Globalization is the process of designing and developing a component that works in different cultures/locales. Use the internationalization library to localize numbers, dates, and times in the Chart component, for example by using the axis labelFormat property.

Numeric Format

The example below globalizes axis, point, and tooltip labels to the EUR currency format.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, ColumnSeries, Legend, Tooltip, DataLabel } from '@syncfusion/ej2-react-charts';
import { setCurrencyCode } from '@syncfusion/ej2-base';
import { data } from './datasource';
setCurrencyCode('EUR');
function App() {
    const primaryxAxis = { edgeLabelPlacement: 'Shift', title: 'Years' };
    const primaryyAxis = { labelFormat: 'c', title: 'Sales Amount in Millions' };
    const marker = { dataLabel: { visible: true } };
    const tooltip = { enable: true, format: '${point.x} : ${point.y}' };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Average Sales Comparison' tooltip={tooltip}>
      <Inject services={[ColumnSeries, Legend, Tooltip, DataLabel]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='Product X' type='Column' marker={marker}>
        </SeriesDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y1' name='Product Y' type='Column' marker={marker}>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}

export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, AxesDirective, AxisDirective, SeriesDirective, Inject,
ColumnSeries, Legend, Tooltip, DataLabel, TooltipSettingsModel, AxisModel }
from'@syncfusion/ej2-react-charts';
import { loadCldr, setCurrencyCode } from '@syncfusion/ej2-base';
import { data } from './datasource';
setCurrencyCode('EUR');

function App() {

  const primaryxAxis: AxisModel = { edgeLabelPlacement: 'Shift', title: 'Years' };
  const primaryyAxis: AxisModel = { labelFormat: 'c', title: 'Sales Amount in Millions' };
  const marker = { dataLabel: { visible: true } };
  const tooltip: TooltipSettingsModel = { enable: true, format: '${point.x} : ${point.y}' };

  return <ChartComponent id='charts'
      primaryXAxis={primaryxAxis}
      primaryYAxis={primaryyAxis}
      title='Average Sales Comparison'
      tooltip={tooltip}>
      <Inject services={[ColumnSeries, Legend, Tooltip, DataLabel]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' name='Product X' type='Column'
          marker={marker}>
        </SeriesDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y1' name='Product Y' type='Column'
          marker={marker}>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>
