Gantt chart for Angular.js

A Gantt chart directive for Angular.js without any other dependencies.

####TRY THE DEMO

Features

  • Usable with or without Bootstrap 3
  • Every task has its own color, subject, date (from, to)
  • Tasks can be moved and are resizable
  • Rows combine multiple tasks and can have independent descriptions
  • Rows can be sorted by description, date and custom order
  • A user can drag&drop a row to sort it in custom mode
  • Events on scroll, click, add or update
  • Configurable (e.g. day or hour scale, weekend days, ..)

Missing / To improve

  • Add support for US week numbers. Currently all week numbers are according to ISO 8106.

Requires

  • Angular.js >= 1.2.16

Usage

Copy the files assets/angular-gantt.js, assets/gantt.css and template/gantt.tmpl.html to your project. For a sample app see the files demo.html and assets/demo.js.

  1. Add the gantt.js and gantt.css files to your HTML code.

     <head><link rel="stylesheet" href="assets/gantt.css"/></head>
 <body><script src="assets/angular-gantt.js"></script></body>

  2. Include the module gantt to your Angular app modules.

     var myApp = angular.module('myApp', ['gantt']);

  3. Put directive gantt into your HTML code at the position you would like to show the Gantt chart.

     <gantt></gantt>

How to build

  1. Install Grunt
  2. Run npm install to install all dependencies
  3. Run grunt to build angular-gantt.js and angular-gantt.min.js

Hint: Use grunt watch to build angular-gantt.js on the fly during development.

Attributes

  • auto-expand (default none)

    The Gantt date range will be extended if the user scroll to the left or right edge. Possible values are both, left, right or none.

  • allow-labels-resizing (default true)

    Defines if the user can resize the row label section by himself.

  • allow-task-moving (default true)

    Defines if tasks can be moved inside a row.

  • allow-task-resizing (default true)

    Defines if tasks can be resized.

  • allow-task-row-switching (default: true)

    If enabled the user can move a task to a different row.

  • allow-row-sorting (default true)

    Defines if the user can sort the rows by himself. This will switch the view-mode to custom as soon as the user starts with the sort.

  • center-date

    Returns a function (fn) which can be called to center the specified date.

    Usage: Specify the gantt property: center-date="scrollToToday = fn"

    In your code call: $scope.scrollToToday(new Date());

  • clear-data

    Returns a function (fn) which can be called to removes all rows and tasks at once. Take a look at the files demo.html and demo.js to see how this callback is used.

  • column-width (default 2)

    How wide are the columns, 1 being 1em. This allows you add logic like column-width="scale == 'day' ? 5 : 2" to have wider columns for days than for other column scales.

  • column-sub-scale (default: 4)

    Defines how precise tasks should be positioned. By default tasks are placed in quarter steps (every 8 hour or 15 minute). Some examples:

    • 4 = in quarter steps
    • 2 = in half steps
    • 24 (if view-scale = day) to display them very accurate

  • first-day-of-week (default: 1)

    Specifies the first day of the week.

    • 0: Sunday
    • 1: Monday
    • 2: Tuesday
    • 3: Wednesday
    • 4: Thursday
    • 5: Friday
    • 6: Saturday

  • from-date

    If specified ensures that the chart is rendered starts at the from-date. This is useful for showing the chart even without any tasks or empty time before the first task.

    Note: At this time this does not truncate the tasks, so you will have to do that to your data

  • to-date

    If specified ensures that the chart is rendered goes at least to the end-date. This is useful for showing the chart even without any tasks or empty time after the last task.

    Note: At this time this does not truncate the tasks, so you will have to do that to your data

  • data

    Allows you to specify the data model for the gantt chart. An example of the data definition can be found in demo_sample_data.js.

  • labels-width (default: 0 = Auto)

    This property defines the width of the label section on the left side of the Gantt. This property support two way binding. Therefore if the user resizes the label section any assigned scope variable will be updated too.

  • load-data

    Returns a function (fn) which can be called to load more data to the Gantt. Take a look at the files demo.html and demo.js to see how this callback is used. An example of the data definition can be found in demo_sample_data.js.

    As an alternative you can use the data property to directly assign the data model.

  • max-height (default: 0 = Disabled)

    If max height is set bigger than 0 the Gantt will be set to this height and show a vertical scroll bar if the content does not fit inside.

  • on-gantt-ready

    This event is raised when the Gantt is initialized and ready to load data.

  • on-label-clicked, on-label-dbl-clicked, on-label-context-clicked

    This event is raised if the user clicks on a row label. Use the evt property on the event to access the original javascript event.

  • on-label-header-clicked, on-label-header-dbl-clicked, on-label-header-context-clicked

    This event is raised if the user clicks on the label header in the top section of the Gantt. Use the evt property on the event to access the original javascript event.

  • on-labels-resized

    This event is raised after the user did resize the row label section.

  • on-row-added and on-row-updated

    Those events are raised if a new row is added or updated. A row is updated if the custom sort order has been changed by the user.

  • on-row-clicked, on-row-dbl-clicked, on-row-context-clicked

    This event is raised if the user clicks on a row. The event has a row, date, column and evt property you can use to detect the date clicked or to access the original javascript event.

  • on-scroll

    This event is raised if the user scrolls to the left or right side of the Gantt chart. Use this event to load more data on the fly.

  • on-task-clicked, on-task-dbl-clicked, on-task-context-clicked

    This event is raised if the user clicks on a task. Use the evt property on the event to access the original javascript event.

  • on-task-updated

    This event is raised if the user moves or resizes a task.

  • on-task-move-begin, on-task-move-end

    This event is raised if when a user starts moving a task and when the move finished.

  • on-task-resize-begin, on-task-resize-end

    This event is raised if when a user starts resizing a task and when the resize operation is finished.

  • remove-data

    Returns a function (fn) which can be called to remove more data from the Gantt. It is possible to remove complete rows or specific tasks. Take a look at the files demo.html and demo.js to see how this callback is used.

  • show-tooltips (default: true)

    Display a tooltip when the user hovers over a task.

  • show-weekend (default: true)

    Display the weekend days if enabled. Weekend days are displayed different than non weekend days.

  • show-non-work-hours (default: true)

    Display the non work hours if enabled. Non work hours displayed different than work hours. Increase the view-scale-factor if you disable this parameter and use view-scale = day as there are less hours displayed per day.

  • sort-mode (default: name)

    Sorts the rows by the given value.

    • name: Sort by row description
    • date: Sort by the earliest task from date of each row
    • custom: Custom sort order using a property called order on each row

    Prepend a - in front to sort descending. E.g. -date

  • template-url (default: template/gantt.tmpl.html)

    URL of the Gantt HTML template. You need to specify this attribute if you put the template in a different folder otherwise the directive won't work.

  • view-scale (default: day)

    Defines the Gantt column scale.

    • hour: Each column is one hour wide
    • day: Each column is one day wide
    • week: Each column is one week wide
    • month: Each column is one month wide

  • weekend-days (default: [0,6])

    Array containing all weekend days. Assign an empty array [] if you don't want any weekend days at all. Example:

    • [0,6]: Sunday, Saturday

  • work-hours (default: [8,9,10,11,12,13,14,15,16])
