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
  }]
}]
