# Calendar heatmap graph
This [d3.js](https://d3js.org/) heatmap representing time series data is used to visualize tracked time over the past year, showing details for each of the days on demand.
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](https://help.github.com/articles/viewing-contributions-on-your-profile/#contributions-calendar)
Based on [Calendar View](https://bl.ocks.org/mbostock/4063318) by [Mike Bostock](https://github.com/mbostock)
Aaand [D3.js Calendar Heatmap](https://github.com/DKirwan/calendar-heatmap) by [Darragh Kirwan](https://github.com/DKirwan)

## Install
- Install 'calendar-heatmap-graph' with bower

bower install calendar-heatmap-graph
```
- Install 'calendar-heatmap-graph' with npm
```
npm install calendar-heatmap-graph
```
- Or include files directly in your html:
```
```
### Properties
|Property | Usage | Default | Required |
|:------------- |:-------------|:-----:|:-----:|
| data | Time series data from max a year back | none | yes |
| container | Div to place the calendar in | placed where function called | no |
| 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
}]
}]
```
Additionally you may specify a color to be used as the primary color for that data point in daily overview, for example:
```
var data = [{
"date": "2017-01-01",
"total": 18456,
"color": "red",
.....
}]
```
### 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
}]
}]
```
