1. Include JSGantt CSS and Javascript

<link rel="stylesheet" type="text/css" href="jsgantt.css" />
<script language="javascript" src="jsgantt.js"></script>

2. Create a div element to hold the gantt chart

<div style="position:relative" class="gantt" id="GanttChartDIV"></div>

3. Start a <script> block

<script language="javascript">

4. Instantiate JSGantt using GanttChart()

var g = new JSGantt.GanttChart('g',document.getElementById('GanttChartDIV'), 'day');


GanttChart(pGanttVar, pDiv, pFormat)
pGanttVar: (required) name of the variable assigned
pDiv: (required) this is a DIV object created in HTML
pFormat: (required) - used to indicate whether chart should be drawn in "day", "week", "month", or "quarter" format

Customize the look and feel using the following setters

g.setShowRes(1); // Show/Hide Responsible (0/1)
g.setShowDur(1); // Show/Hide Duration (0/1)
g.setShowComp(1); // Show/Hide % Complete(0/1)
g.setCaptionType('Resource');  // Set to Show Caption (None,Caption,Resource,Duration,Complete)
g.setShowStartDate(1); // Show/Hide Start Date(0/1)
g.setShowEndDate(1); // Show/Hide End Date(0/1)
g.setDateInputFormat('mm/dd/yyyy')  // Set format of input dates ('mm/dd/yyyy', 'dd/mm/yyyy', 'yyyy-mm-dd')
g.setDateDisplayFormat('mm/dd/yyyy') // Set format to display dates ('mm/dd/yyyy', 'dd/mm/yyyy', 'yyyy-mm-dd')
g.setFormatArr("day","week","month","quarter") // Set format options (up to 4 : "minute","hour","day","week","month","quarter")

5. Add Tasks using AddTaskItem()

g.AddTaskItem(new JSGantt.TaskItem(1,   'Define Chart API',     '',          '',          'ff0000', 'http://help.com', 0, 'Brian',     0, 1, 0, 1));
g.AddTaskItem(new JSGantt.TaskItem(11,  'Chart Object',         '2/10/2008', '2/10/2008', 'ff00ff', 'http://www.yahoo.com', 1, 'Shlomy',  100, 0, 1, 1, "121,122", "My Caption"));
TaskItem(pID, pName, pStart, pEnd, pColor, pLink, pMile, pRes, pComp, pGroup, pParent, pOpen, pDepend)
pID: (required) is a unique ID used to identify each row for parent functions and for setting dom id for hiding/showing
