How to create a pie chart in React

Chibueze Sam-Obisike

Overview

Building charts in React can be complex and daunting. However, there is a lightweight library that can help us build charts quickly in no time.

In this shot, we'll be using the react-minimal-pie-chart package to create charts and customize them using various libraries to make them look professional.

Here's what we've to do:

  1. Use create-react-app to start and create our React app.
  2. Install the minimal-pie-chart using npm i react-minimal-pie-chart.
  3. We go to our app.js file and pass various props into the <PieChart/> component.

Example

import React from 'react';
import ReactDOM from 'react-dom';
import App from './app.js';
require('./style.css');

ReactDOM.render(
  <App />, 
  document.getElementById('root')
);

Explanation

Here’s how we can modify charts using the following properties:

  • animate: This is a boolean that animates elements on the mount.
  • animationDuration: This is the time in milliseconds to which we want the animation to occur.
  • animationEasing: This is the way we want the animation to ease as per the various CSS easing types.
  • center: The x and y coordinates, relative to the center.
  • data: An array of objects containing information about the object. Each object contains a title, color, and value key.
  • lineWidth: This is the line width of each of the pie chart segments.
  • lengthAngle: Total angle taken by the chart that can be negative or positive.
  • paddingAngle: This is the angle between two segments of the pie chart.
  • radius: This is the radius of the chart relative to the view box.
  • rounded: This is a boolean that rounds each cap element segment.
  • startAngle: Start angle of the first segment.
  • viewBoxSize: Width and Height of SVG viewBox attribute.
  • labelStyle: Each label has a style object applied to it. Returns the style for each label if the function is set.
  • label: A label value or the SVG element to be presented as label is returned by this method.
  • labelPosition: Position of the label with relation to the origin. Percentage of the radius of the chart.

With these properties, we're able to build applications and integrate pie charts into them.
