Example

Code it yourself on the Visualization Playground

<html>
  <head>
    <script type='text/javascript' src='http://www.google.com/jsapi'></script>
    <script type='text/javascript'>
      google.load('visualization', '1', {packages:['orgchart']});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Name');
        data.addColumn('string', 'Manager');
        data.addColumn('string', 'ToolTip');
        data.addRows([
          [{v:'Mike', f:'Mike<div style="color:red; font-style:italic">President</div>'}, '', 'The President'],
          [{v:'Jim', f:'Jim<div style="color:red; font-style:italic">Vice President<div>'}, 'Mike', 'VP'],
          ['Alice', 'Mike', ''],
          ['Bob', 'Jim', 'Bob Sponge'],
          ['Carol', 'Bob', '']
        ]);
        var chart = new google.visualization.OrgChart(document.getElementById('chart_div'));
        chart.draw(data, {allowHtml:true});
      }
    </script>
  </head>

  <body>
    <div id='chart_div'></div>
  </body>
</html>

Loading

The google.load package name is 'orgchart' 

  google.load('visualization', '1', {packages: ['orgchart']});

The visualization's class name is google.visualization.OrgChart 

  var visualization = new google.visualization.OrgChart(container);

Data Format

A table with three string string columns, where each row represents a node in the orgchart. Here are the three columns:

  • Column 0 - The node ID. It should be unique among all nodes, and can include any characters, including spaces. This is shown on the node. You can specify a formatted value to show on the chart instead, but the unformatted value is still used as the ID.
  • Column 1 - [optional] The ID of the parent node. This should be the unformatted value from column 0 of another row. Leave unspecified for a root node.
  • Column 2 - [optional] Tool-tip text to show, when a user hovers over this node.

Each node can have zero or one parent node, and zero or more child nodes.

Custom Properties

You can assign the following custom properties to data table elements, using the setProperty() method of DataTable:

Property Name Applies To Description
selectedStyle DataTable row

An inline style string to assign to a specific node when selected. You must set the option allowHtml=true for this to work, and it must be set before calling draw() on the visualization. This overrides the selectionColor option for the specified node.

Example:   myDataTable.setRowProperty(2, 'selectedStyle', 'background-color:#00FF00');
style DataTable row

An inline style string to assign to a specific node. This is overridden by the selectedStyle property. You must set the option allowHtml=true for this to work, and it must be set before calling draw() on the visualization. This overrides the color option for the specified node.

Example:  myDataTable.setRowProperty(3, 'style', 'border: 1px solid green;'.

Configuration Options

Name Type Default Description
allowCollapse boolean false Determines if double click will collapse a node.
allowHtml boolean false If set to true, names that includes HTML tags will be rendered as HTML.
color string '#edf7ff' Deprecated. Use nodeClass instead. The background color of the orgchart elements.
nodeClass string default class name A class name to assign to node elements. Apply CSS to this class name to specify colors or styles for the chart elements.
selectedNodeClass string default class name A class name to assign to selected node elements. Apply CSS to this class name to specify colors or styles for selected chart elements.
selectionColor string '#d6e9f8' Deprecated. Use selectedNodeClass instead. The background color of selected orgchart elements.
size string 'medium' 'small', 'medium' or 'large'

Methods

Method Return Type Description
collapse(row, collapsed) none Collapses or expands the node.
  • row - Index of the row to expand or collapse.
  • collapsed Whether to collapse or expand the row, where true means collapse.
draw(data, options) none Draws the chart.
getChildrenIndexes(row) Array.<number> Returns an array with the indexes of the children of the given node.
getCollapsedNodes Array.<number> Returns an array with the list of the collapsed node's indexes.
getSelection() Array of selection elements Standard getSelection() implementation. Selection elements are all row elements. Can return more than one selected row.
setSelection(selection) none Standard setSelection() implementation. Treats every selection entry as a row selection. Supports selection of mutiple rows.

Events

Name Description Properties
collapse Event triggered when allowCollapse is set to true and the user double clicks on a node with children.

collapsed - A boolean indicating whether this is a 'collapse' or 'expand' event.

row - The zero-based index of the row in the data table, corresponding to the node being clicked.
onmouseover Triggered when the user hovers over a specific row. row - The zero-based index of the row in the data table, corresponding to the node being moused over.
onmouseout Triggered when the user hovers out of a row. row - The zero-based index of the row in the data table, corresponding to the node being moused out from.
select Standard select event None
ready The chart is ready for external method calls. If you want to interact with the chart, and call methods after you draw it, you should set up a listener for this event before you call the draw method, and call the methods only after the event is fired. None
