Plotly is a free and open-source graphing library for JavaScript. We recommend you read our Getting Started guide for the latest installation or upgrade instructions, then move on to our Plotly Fundamentals tutorials or dive straight in to some Basic Charts tutorials.

Basic Horizontal Bar Chart

var data = [{
  type: 'bar',
  x: [20, 14, 23],
  y: ['giraffes', 'orangutans', 'monkeys'],
  orientation: 'h'
}];

Plotly.newPlot('myDiv', data);

Colored Bar Chart

var trace1 = {
  x: [20, 14, 23],
  y: ['giraffes', 'orangutans', 'monkeys'],
  name: 'SF Zoo',
  orientation: 'h',
  marker: {
    color: 'rgba(55,128,191,0.6)',
    width: 1
  },
  type: 'bar'
};

var trace2 = {
  x: [12, 18, 29],
  y: ['giraffes', 'orangutans', 'monkeys'],
  name: 'LA Zoo',
  orientation: 'h',
  type: 'bar',
  marker: {
    color: 'rgba(255,153,51,0.6)',
    width: 1
  }
};

var data = [trace1, trace2];

var layout = {
  title: 'Colored Bar Chart',
  barmode: 'stack'
};

Plotly.newPlot('myDiv', data, layout);
