chartjs-plugin-doughnut-innertext v3.1.0

Chart JS Line Height Annotation Plugin

PRs Welcome

A small, lightweight and reliable ChartJS plugin for Doughnut charts specifically. This plugin was made to be compatible with the react-chartjs-2 library, but it is available as a commonjs and umd module, as well.

Usage

npm i chartjs-plugin-doughnut-innertext

For React components:

import React, { Component } from "react";
import { Doughnut } from "react-chartjs-2";
import "chartjs-plugin-doughnut-innertext";

class App extends Component {
  render() {
    let data = api.get("doughnut-data");
    return (
      <Doughnut
        options={{
          // see all defaults / options below!
          centerText: {
            color: "#000",
            value: 340,
            fontSizeAdjust: 0.2 // increase font size 20% based on default font size
          }
        }}
        data={data}
      />
    );
  }
}

  // color of the text
