How to apply custom fonts for legend in React Chart?

This article explains how to customize the legend font in React Chart.

Customize the font of legend

You can set a custom font family to all the text elements in the chart. You can easily customize the legend font by using the fontFamily, fontWeight, fontStyle, size, and color properties within the textStyle property of the legend.

In the following code example, the legend font is customized by using the fontStyle, fontWeight, and color properties.

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

const Column = () => {
 return (

             color: 'blue'
           }
