Calendar Heatmap QlikView Extension (D3CalendarView)

I have recently published a free calendar heatmap extension to compare values on a day-per-day basis over a long period of time (several years). The extension is developed using D3 and an existing visualization called “Calendar View” by Mike Bostok.

The data passed to the extension is displayed in a diverging color scale. The values are visualized as colored cells per day. Days are arranged into columns by week, then grouped by month and years.


Example 1 - Displaying Historical Dow Jones Data

Example 2 - Visualizing U.S. Commercial Flights

Usage Scenarios

There are several scenarios where using this extension seems to be a helpful kind of visualization:

  • Comparing changes of stock exchange prices
  • Making out of stock trends visible
  • etc.

Download, Configuration & Source Code

The source code, a demo-application and the .qar files are published on GitHub, where you will also find a short description how to configure the extension.

GitHub-Repository to post issues, fork the source-code, etc.:
