Essential JS 2 Charts in React — Getting Started, Examples & Customization
Essential JS 2 Charts in React — Getting Started, Examples & Customization
This guide explains how to install, set up and customize Essential JS 2 charts for React applications, with practical examples (line, bar, pie), dashboard considerations and optimization tips. It is targeted at React developers who need a production-ready chart library (fast, feature-rich, and customizable) without wading through fragmented docs.
1. Quick SEO analysis of the English SERP for your keywords
I analyzed the typical top-10 results for queries like "essential js 2 charts", "React Syncfusion charts", and "essential js 2 charts tutorial". The SERP mix is dominated by:
– Official product pages and documentation from Syncfusion (high-authority, comprehensive API and demos).
– Developer tutorials on blogs (Dev.to, Medium, personal blogs) showing "getting started" and code examples.
– Q&A (StackOverflow) and GitHub issues addressing setup/compatibility problems.
Intents found: informational (tutorials, how-tos, examples), navigational (official docs, npm packages), and some commercial intent (Syncfusion product pages & licensing). The highest-visibility pages are practical guides with clear setup steps and runnable code samples — those are the pages that get featured snippets and PAA entries.
2. Competitor content structure & depth
Top competitors commonly follow this structure: quick intro → installation/requirements → basic "Hello chart" example → multiple chart types (line/bar/pie) → customization (colors, tooltip, legend) → advanced topics (real-time, export, performance) → live demos & API links. Official docs are deep (API reference, props, methods) while blog posts focus on "how to get a chart working in 10 minutes".
Gaps you can exploit: short, clear voice-search-optimized steps for installation and code snippets; concise explanations of common pitfalls (React hooks, SSR, bundlers); pattern examples for dashboards and real-time updates. Combining a small but complete "getting started" with a real-world dashboard example tends to win featured snippets.
Recommendation: produce one authoritative how-to that answers the most common quick queries (install, example, customize) and embeds authoritative links (Syncfusion docs, npm, example tutorial) — that captures both featured-snippet intent and navigational clicks.

Getting started: install and setup Essential JS 2 charts in React
The quickest path to a working chart is to add Syncfusion's React charts package and render a basic component. The official package is @syncfusion/ej2-react-charts. If you prefer a guided walkthrough, this dev.to tutorial is a practical companion with runnable examples.
Typical setup steps: ensure Node 14+/React 16.8+ (hooks-friendly), install the chart package and required theme CSS, then render the chart component with a data source. Note: Syncfusion components are framework-wrapped so you use React components instead of manual DOM manipulation — that keeps React's reconciliation intact.
Minimal commands (one-time):
- npm install –save @syncfusion/ej2-react-charts @syncfusion/ej2-charts @syncfusion/ej2-base
For the latest official installation docs and options (including CDN and ES module builds) see the Syncfusion docs: Syncfusion React Charts — Getting Started.
Basic example: line, bar and pie charts (code + explanation)
Once installed, the pattern is the same for most chart types: import the React chart components, provide a typed data array, configure axes/series, and render. The library exposes typed series components (LineSeries, ColumnSeries, PieSeries) with props for common features like marker, tooltip and legend.
Example (conceptual snippet — paste into a React component). This uses the Line chart as the canonical example because it demonstrates axes, series and tooltips. Replace the series type for bar/column or use <AccumulationChart> for pie charts in Syncfusion.
// conceptual example (React)
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, LineSeries, Tooltip, Legend } from '@syncfusion/ej2-react-charts';
const data = [
{ x: 'Jan', y: 35 },
{ x: 'Feb', y: 28 },
{ x: 'Mar', y: 34 },
// ...
];
export default function MyLineChart() {
return (
<ChartComponent primaryXAxis={{ valueType: 'Category' }} tooltip={{ enable: true }} >
<Inject services={[LineSeries, Tooltip, Legend]} />
<SeriesCollectionDirective>
<SeriesDirective dataSource={data} xName='x' yName='y' type='Line' marker={{ visible: true }} />
</SeriesCollectionDirective>
</ChartComponent>
);
}
Switch type='Line' to 'Column' for a bar chart (React bar chart) and use the AccumulationChart family for pie charts (React pie chart). The library provides examples and live samples in the docs and demos — a great source for copying specific props like stacking, multi-axis or datetime axes.

Customization and theming: colors, tooltips, legends, annotations
Customization is deliberate and prop-driven. You can adjust series colors, marker shapes, gradients, tooltip templates and legend behavior via props or by overriding the theme CSS. The advantage of Essential JS 2 is a consistent API across chart types — once you learn the pattern you can move between line, bar and pie charts quickly.
Example customizations to consider:
- Tooltip templates for rich HTML tooltips or formatted values
- Legend toggling and custom legend templates
- Annotations and markers to highlight thresholds
Avoid inline heavy DOM operations for performance. Use the provided props (e.g., tooltip.template, marker.shape, pointColorMapping) and the theme API instead. Also, for dashboards, consider lazy-loading charts that are off-screen to speed initial render.
Dashboard patterns & real-time updates
Building a dashboard requires composition: multiple chart components, shared state (for filters), and attention to rendering performance. Syncfusion charts are reasonably performant, but you must take care with very large datasets and frequent updates.
Strategies for better performance:
- Virtualize or downsample data on the client or server for large time-series.
- Throttle updates (batch state changes) when receiving real-time streams.
For real-time feeds, update only the series data and call the chart's refresh method where appropriate. The library supports partial updates so you don’t always re-render everything. Also consider Web Worker preprocessing for heavy computations before rendering in the main thread.
Production tips, licensing and deployment
Syncfusion's Essential JS 2 components are production-ready. There are licensing considerations: Syncfusion provides a community license for qualifying users and commercial licenses for enterprises. Check the official licensing page before deployment if your project is commercial.
For bundlers, ensure tree-shaking by importing only needed packages (e.g., import specific services rather than whole bundles). Also include the theme CSS once (usually in index.js or entry file) to avoid redundant downloads.

FAQ
How do I install Essential JS 2 charts in a React project?
Install the package via npm: npm install --save @syncfusion/ej2-react-charts @syncfusion/ej2-charts, import the required chart components and services in your React component, and include the Syncfusion CSS theme in your entry file. See the official getting-started docs for exact import and bundler notes.
How to create a basic line/bar/pie chart example?
Import ChartComponent and the matching series directive (LineSeries/ColumnSeries or AccumulationChart for pie). Provide a dataSource array and set xName and yName on the series. Enable tooltip and legend via props. The dev.to tutorial linked above has a step-by-step example you can copy and run.
Is Essential JS 2 free for production use?
Syncfusion offers a free community license under specific conditions (individuals and small companies) and commercial licenses for others. Evaluate your project's licensing needs against Syncfusion's terms — when in doubt, consult their licensing page.
