Overview

This article demonstrates the steps required to create a basic Resource Gantt chart from scratch.

Modules

AnyGantt requires adding two modules - Core and Gantt. Place a link to two JavaScript files in the <head> section of your web page.

Note: These files can be downloaded from the AnyChart download page.

<head>
  <script src="https://cdn.anychart.com/releases/8.13.0/js/anychart-core.min.js" type="text/javascript"></script>
  <script src="https://cdn.anychart.com/releases/8.13.0/js/anychart-gantt.min.js" type="text/javascript"></script>
</head>

Container

Add a block-based HTML element to your page, set the id, width, and height attributes. AnyChart charting library uses 100% of the container if other behavior is not specified.

<body>
  <div id="container"></div>
<body>

Data

AnyGantt requires using the tree data model. This is how your data should be organized for it:

// create data
var data = [
  {
    id: "1",
    name: "Server 1",
    periods: [
      {id:"1_1", start: "2018-01-05", end: "2018-01-25"},
      {id:"1_2", start: "2018-01-28", end: "2018-02-22"},
      {id:"1_3", start: "2018-03-03", end: "2018-03-25"}
  ]},
  {
    id: "2",
    name: "Server 2",
    periods: [
      {id: "2_1", start: "2018-01-07", end: "2018-02-15"},
      {id: "2_2", start: "2018-02-26", end: "2018-03-20"}
  ]},
  {
    id: "3",
    name: "Server 3",
    periods: [
      {id: "3_1", start: "2018-01-04", end: "2018-03-25"}
  ]}
];

Chart

To create a chart, add the JavaScript tag <script> with the code below.

<script>
  anychart.onDocumentReady(function () {    	
    // create data
    var data = [
      {
        id: "1",
        name: "Server 1",
        periods: [
          {id:"1_1", start: "2018-01-05", end: "2018-01-25"},
          {id:"1_2", start: "2018-01-28", end: "2018-02-22"},
          {id:"1_3", start: "2018-03-03", end: "2018-03-25"}
      ]},
      {
        id: "2",
        name: "Server 2",
        periods: [
          {id: "2_1", start: "2018-01-07", end: "2018-02-15"},
          {id: "2_2", start: "2018-02-26", end: "2018-03-20"}
      ]},
      {
        id: "3",
        name: "Server 3",
        periods: [
          {id: "3_1", start: "2018-01-04", end: "2018-03-25"}
      ]}
    ];
    // create a data tree
    var treeData = anychart.data.tree(data, "as-table");  
    // create a chart
    var chart = anychart.ganttResource(); 
    // set the data
    chart.data(treeData); 
    // set the container id
    chart.container("container");  
    // initiate drawing the chart
    chart.draw();
    // fit elements to the width of the timeline
    chart.fitAll();
  });  
</script>

Sample

This sample demonstrates the result of the steps above. Like any other sample, it can be launched and modified in AnyChart Playground.
