angular-calendar-heatmap

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 :)

Inspired by Github's contribution chart.

Based on 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 for each day going 1 year back. Each day has a total time tracked (in seconds). Details, if provided, are shown in a tooltip as well as in daily overview.

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
  }]
}]
