ember-timetree

Visualize hierarchical timeline data. Built with Ember.js and D3.js.

Peep the demo.

Installation

ember install:addon ember-timetree

Basic Usage

{{time-tree content=yourTimetreeArray}}

where YourTimetreeArray is an array of objects representing the rows of the timetree.

Row Object

Each row object is a plain JavaScript object defining at least a display name, a start time, and an end time. Here is the full set of fields.

{
  /* REQUIRED FIELDS */
 
  label:     "Name",
  start:     12345,      // Milliseconds since the UTC epoch.
  end:       67890,
 
  /* OPTIONAL FIELDS */
 
  parent:    3,          // Index of this row's hierarchical parent in the array.
  id:        "123456L",  // Id for determining uniqueness; defaults to index in the array.
  className: "info",     // CSS class name for this row's labels and bars.
 
  content:   {},         // Arbitrary content to bind when the user selects (clicks on) a
                         // row. Useful if you want to do exact identity comparison to the
                         // selection. If empty, selecting a row binds `content` to the
                         // row object itself (which ember-timetree may have transformed,
                         // so don't count on it being identical to your original input).
 
  sections:  [{ start: 12345, end: 23456, className: "active"   },  // Start/stop this row's timeline multiple times.
              { start: 23456, end: 67890, className: "inactive" }]  // Each section can have its own, optional CSS class name.
                                                                    // Note the row object's overall start/end fields must
                                                                    // still be specified above, as its bar will still be drawn.
}

More Options

Selection

To bind to the currently selected row of the timetree, set the time-tree's selection attribute. Upon the user selecting a row, the binding will contain the selected row's content field, or the row object itself if content is empty.

ember-timetree won't transform the content field but it may transform the row object, so don't count on the latter being identical to your original input.

Resize on Collapse

If you set the resizeOnCollapse attribute to true, the height of the tree will resize when collapsing a node. This is nice when you have really long tree and you do not want white space when a node is collapsed.

Brush View

Want to zoom and drag to focus anywhere on your timeline? After the main view, add a {{time-tree-brush}}, and link the two via the range and brushRange attributes, respectively.

{{time-tree content=yourTimetreeArray range=yourRange}}
{{time-tree-brush content=yourTimetreeArray brushRange=yourRange}}

Extending

Many methods on time-tree can be extended. For example, to override the built-in date/time format:

import Ember from 'ember';
 
import TimeTreeComponent from 'ember-timetree/components/time-tree';
 
const MyTimeTreeComponent = TimeTreeComponent.extend({
  timeFormat: Ember.computed(function() {
    /* global d3 */
    return d3.time.format.utc("your D3 date format here");
  }).property()
});
 
export default MyTimeTreeComponent;
 

Default View Options

width:          750,
rowHeight:      15,
rowSpacing:     10,
labelsWidth:    200,
axisHeight:     20,
axisPosition:   'bottom',
indentSize:     20,
labelAlign:     'left',
contentMargin:  null,      // e.g. { top: 0, left: 0, bottom: 0, right: 0 },
 
collapsable:    true,      // can collapse hierarchy items?
resizeOnCollapse: false,   // resize the height of the tree when collapsing a node
scrubbable:     true,      // draw the scrubber (on hover)?
selectable:     true,      // can select rows (on click)?
brushable:      false,     // can drag-click and drag to zoom?
 
showLabels:     true,
showLinks:      true,
 
content:        null,      // bind this to the array of row objects
selection:      null,      // bind this to the selected row
brushRange:     null,      // bind this to a TimetreeBrushView
