Syncfusion React Charts

Implementing Syncfusion React Charts

When to Use This Skill

Use this skill when you need to:

• Create and render charts (area, bar, column, line, scatter, etc.)
• Configure chart axes and customize their appearance
• Bind local data, remote data (DataManager), or use OData/WebAPI/custom adaptors
• Dynamically add, remove, or replace data points (addPoint, removePoint, setData)
• Customize chart appearance (colors, labels, legends, annotations)
• Configure data labels (must be placed inside marker.dataLabel, not directly on the series)
• Implement user interactions (selection, zooming, tooltips)
• Add financial indicators and technical analysis
• Handle accessibility and internationalization
• Troubleshoot chart rendering or data issues

Quick Start Example

import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, LineSeries, Category, Legend, Tooltip } from '@syncfusion/ej2-react-charts';

export default function BasicChart() {
  const data = [
    { x: 'Jan', y: 35 },
    { x: 'Feb', y: 28 },
    { x: 'Mar', y: 34 },
    { x: 'Apr', y: 32 },
    { x: 'May', y: 40 }
  ];

  return (
    <ChartComponent id='charts'>
      <Inject services={[LineSeries, Category, Legend, Tooltip]} />
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={data} xName='x' yName='y' type='Line' />
      </SeriesCollectionDirective>
    </ChartComponent>
  );
}

Common Patterns

Pattern 1: Multi-Series Chart

When displaying multiple datasets that share the same axes, add multiple SeriesDirective components within SeriesCollectionDirective:

<SeriesCollectionDirective>
  <SeriesDirective dataSource={salesData} xName='month' yName='revenue' type='Column' />
  <SeriesDirective dataSource={profitData} xName='month' yName='profit' type='Column' />
</SeriesCollectionDirective>

Pattern 2: Dynamic Data Updates

Three approaches depending on the use case:

a) React state (simple re-render):

const [data, setData] = useState(initialData);

const handleDataUpdate = () => {
  setData(prev => [...prev, { x: 'Jun', y: 45 }]);
};

<SeriesDirective dataSource={data} xName='x' yName='y' type='Line' />

b) addPoint / removePoint / setData (imperative, with animation):

const chartRef = useRef(null);

// Add a point
chartRef.current.series[0].addPoint({ x: 'Jun', y: 45 }, 300);

// Remove first point
chartRef.current.series[0].removePoint(0, 300);

// Replace all data
chartRef.current.series[0].setData(newDataArray, 500);

<ChartComponent ref={chartRef} ...>
  <SeriesDirective dataSource={data} xName='x' yName='y' type='Line' />
</ChartComponent>

Pattern 3: Remote Data Binding

Use DataManager with an adaptor to bind data from a REST API or OData service:

import { DataManager, Query, WebApiAdaptor } from '@syncfusion/ej2-data';

const dataManager = new DataManager({
  url: 'your data source URL link',
  adaptor: new WebApiAdaptor()
});

<SeriesDirective dataSource={dataManager} xName='CustomerID' yName='Freight' type='Column' query={new Query()} />

Other adaptors: ODataAdaptor (OData v3), ODataV4Adaptor (OData v4), custom adaptor by extending ODataAdaptor.

Pattern 4: Data Labels (inside marker)

Data labels must be placed inside marker.dataLabel, not directly on the series. Inject DataLabel service:

<Inject services={[LineSeries, Category, DataLabel]} />

<SeriesDirective
  dataSource={data}
  xName='x'
  yName='y'
  type='Line'
  marker={{
    visible: true,
    dataLabel: { visible: true, position: 'Top' }
  }}
/>

Pattern 5: Custom Tooltips

Enhance user experience with formatted tooltip templates:

<ChartComponent tooltip={{ enable: true, template: '<div>${point.x}: ${point.y}</div>' }}>

Pattern 6: Responsive Design

Use container styling to make charts responsive:

<ChartComponent id='charts' width='100%' height='400px'>
  {/* chart content */}
</ChartComponent>

Common Use Cases

1. Sales Dashboard: Combine column chart for revenue with line series for trends
2. Time Series Analysis: Use date-time axis with line chart for temporal data
3. Comparative Analysis: Multi-series column charts comparing categories
4. Financial Analysis: Candlestick chart with moving average indicators
5. Distribution Analysis: Histogram or box-whisker charts for statistical data
6. Real-time Monitoring: Use addPoint/removePoint for live feeds with smooth animation
7. Remote Data from REST API: Bind DataManager with WebApiAdaptor or ODataAdaptor directly to series
8. Server-side OData: Use ODataV4Adaptor with a Query to filter and paginate at the server
