Install

npm install frappe-gantt

Usage

Include it in your HTML:

<script src="frappe-gantt.min.js"></script>
<link rel="stylesheet" href="frappe-gantt.css">

And start hacking:

var tasks = [
  {
    id: 'Task 1',
    name: 'Redesign website',
    start: '2016-12-28',
    end: '2016-12-31',
    progress: 20,
    dependencies: 'Task 2, Task 3',
    custom_class: 'bar-milestone' // optional
  },
  ...
];
var gantt = new Gantt("#gantt", tasks);

You can also pass various options to the Gantt constructor:

var gantt = new Gantt("#gantt", tasks, {
    header_height: 50,
    column_width: 30,
    step: 24,
    view_modes: ['Quarter Day', 'Half Day', 'Day', 'Week', 'Month'],
    bar_height: 20,
    bar_corner_radius: 3,
    arrow_curve: 5,
    padding: 18,
    view_mode: 'Day',   
    date_format: 'YYYY-MM-DD',
    custom_popup_html: null
});

Multiple periods per Task

Although uncommon in GANTT charts you can specify an additional array for the periods key of a task to show additional bars in the task row of the generated chart

The following example shows the task from above with three additional periods:

var tasks = [
  {
    id: 'Task 1',
    name: 'Redesign website',
    start: '2016-12-28',
    end: '2016-12-31',
    progress: 20,
    dependencies: 'Task 2, Task 3',
    custom_class: 'bar-milestone', // optional
    periods: [
    	{
    		start: '2017-01-05',
    		end: '2017-01-07'
    	},
    	{
    		start: '2017-01-09',
    		end: '2017-01-14'
    	},
    	{
    		start: '2017-01-15',
    		end: '2017-01-17'
    	}
    ]
  },
  ...
];
var gantt = new Gantt("#gantt", tasks);

Supported formats for start and end keys of each object in periods are the same as for start and end on the main task definition. Please be advised, that it is not supported to enable mouse events for tasks that have periods. You should disable user interaction for the task bar manipulation if you use the period feature.

Due to the structure of the library even if you use periods you have to specify a start and end attribute for the task. If e.g. you want bars inside the row of a task the first period is specified in start and end and the second one in the periods attribute:

var tasks = [
  {
    id: 'task1',
    name: 'two time period task',
    start: '2016-12-28',
    end: '2016-12-31',
    periods: [
    	{
    		start: '2017-01-05',
    		end: '2017-01-07'
    	}
    ]
  }
];
var gantt = new Gantt("#gantt", tasks);

If a period is clicked, the period definition is passed to the on_click handler as second parameter after the task.

Checkpoints

If you want to display a diamond shaped item for a task to indicate a checkpoint you can specify a period with the key type set to checkpoint. This will render a diamond shape at the specified start date.

var tasks = [
  {
     id: 'task1',
     name: 'My checkpoint task',
     start: '2016-12-28',
     end: '2016-12-31',
     periods: [
     	{
            type: 'checkpoint',
            start: '2017-01-05'
     	}
     ]
   }
];

Custom CSS class and fill color

If you want to specify custom classes for tasks and/or periods you may do so with the custom_class or fill property. Task classes specifed via custom_class on task level are inherited to its periods. This is also true for the fill property. However, if a period defines a fill property it overrides the one specified on task level, whereas a custom_class on period level is simply added alongside a custom_classon task level.

var tasks = [
  {
     id: 'task1',
     name: 'My checkpoint task',
     start: '2016-12-28',
     end: '2016-12-31',
     custom_class: 'my-task-css-class',
     periods: [
     	{
            start: '2017-01-05',
            end: '2017-01-07'
     	},
     	{
            start: '2017-01-08',
            end: '2017-01-09',
            custom_class: 'my-period-css-class',
            fill: '#ff0000'
     	}
     ]
   }
];

var gantt = new Gantt("#gantt", tasks);
