Angular directive for D3.js Calendar Heatmap

This d3.js heatmap representing time series data is used to visualize tracked time over the past year, showing details for each of the days on demand. Converted into an angular directive for your convenience :)

Includes a global overview of multiple years and visualizations of year, month, week and day overview with zoom for details-on-demand.

Inspired by Github's contribution graph

Based on Calendar View by Mike Bostock
Aaand D3.js Calendar Heatmap by Darragh Kirwan

Installation

  1. Install 'angular-calendar-heatmap' with bower
bower install angular-calendar-heatmap

Or:

npm install angular-calendar-heatmap
  1. Add 'g1b.calendar-heatmap' module to your app config
angular.module('myApp', [
  'g1b.calendar-heatmap',
  .....
])
  1. Use 'calendar-heatmap' directive in a view
<calendar-heatmap data="example_data" color="'#ff0000'" overview="'year'" handler="print"></calendar-heatmap>

Attributes

Property Usage Default Required
data Time series data from max a year back none yes
color Theme hex color #45ff00 no
overview Initial overview type (choices are: year, month, day) year no
handler Handler function is fired on click of a time entry in daily overview none no

Example data

Time series data where each day has a total time tracked (in seconds).
Details, if provided, are shown in a tooltip on mouseover in different overviews.

var data = [{
  "date": "2016-01-01",
  "total": 17164,
  "details": [{
    "name": "Project 1",
    "date": "2016-01-01 12:30:45",
    "value": 9192
  }, {
    "name": "Project 2",
    "date": "2016-01-01 13:37:00",
    "value": 6753
  },
  .....
  {
    "name": "Project N",
    "date": "2016-01-01 17:52:41",
    "value": 1219
  }]
}]

Optimization

In some cases details array could be large and in order to fit the data into the tooltip a short summary is generated with distinct projects and their total tracked time for that date. In terms of optimization, summary data can be computed server-side and passed in using the summary attribute. And in addition to the data structure described above this would result in a summary dictionary with distinct project names and total values of tracked time in seconds, e.g.:

var data = [{
  "date": "2016-01-01",
  "total": 17164,
  "details": [.....],
  "summary": [{
    "name": "Project 1",
    "value": 9192
  }, {
    "name": "Project 2",
    "value": 6753
  },
  .....
  {
    "name": "Project N",
    "value": 1219
  }]
}]
