I use Nozbe as a system for task management and I couldn’t have a broader view of what is
planned in the coming weeks. Using the Nozbe API, Google Chart API and tasks tagging I’ve created a chart that can help.
The only thing you have to do, is to create categories in the format like 2016.01, 2016.02 (where 01, 02 is a number of weeks, not months) and assign tasks to them. What’s more – tasks can belong to multiple categories, so you do not have to give up the current assignment.
Sample chart is available at http://skaruz.com/projects/nozbe/charts.php
Code is available upon request.
