BarChart

A React component for rendering bar charts using Chart.js, with additional features to maintain consistent label widths across multiple charts.

Installation

You can install this package using npm or yarn:

npm install chartjs-barchart

or

yarn add chartjs-barchart

Features

Chart.js bar charts don't provide a built-in feature to set a fixed label width, which can lead to inconsistent widths and heights when displaying multiple charts. This component addresses these issues by allowing you to set a consistent label width, ensuring uniformity across all your charts.

Usage

First, import the BarChart component into your React application:

Note

When the type prop is set to "vertical", the labelWidth and labelTextLength props will not be applied, as they are specific to horizontal bar charts.

import React from 'react';
import BarChart from 'chartjs-barchart';

const App = () => {
  const data = {
    labels: ['Label 1', 'Label 2', 'Label 3'],
    datasets: [
      {
        label: 'Dataset 1',
        data: [10, 20, 30],
        backgroundColor: 'rgba(75, 192, 192, 0.6)',
      },
    ],
  };

  const options = {
    scales: {
      x: {
        beginAtZero: true,
      },
    },
  };

  return (
    <div>
      <h1>Bar Chart</h1>
      <BarChart
        data={data}
        options={options}
        labelWidth={300}
        labelTextLength={10}
        type="horizontal" // Can be "horizontal" or "vertical"
      />
    </div>
  );
};

export default App;

Props

The BarChart component accepts the following props:

• data (required): The chart data, structured as per Chart.js documentation.
• options (optional): Custom options for the chart, structured as per Chart.js documentation.
• labelWidth (optional): Custom width for the labels on the y-axis. Default is 400.
