Dependencies

Usage

1: Add d3.js and moment.js

2: Include calendar-heatmap.js and calendar-heatmap.css <link rel="stylesheet" type="text/css" href="path/tocalendar-heatmap.css"> <script src="path/to/calendar-heatmap.js"></script>

3: Format the data so each array item has a date and count property. As long as new Date() can parse the date string it’s ok. Note - there all data should be rolled up into daily bucket granularity.

4: Configure the chart and render it

// chart data example
var chartData = [{
  date: valid Javascript date object,
  count: Number
}];
var chart1 = calendarHeatmap()
              .data(chartData)
              .selector('#chart-one')
              .colorRange(['#D8E6E7', '#218380'])
              .tooltipEnabled(true)
              .onClick(function (data) {
                console.log('onClick callback. Data:', data);
              });
chart1();  // render the chart

control unit pluralization

var chart1 = calendarHeatmap()
              .data(chartData)
              .tooltipUnit(
                [
                  {min: 0, unit: 'contribution'},
                  {min: 1, max: 1, unit: 'contribution'},
                  {min: 2, max: 'Infinity', unit: 'contributions'}
                ]
              );
chart1();  // render the chart
