Burn-up chart tracks your progress in completing tasks.
Currently my major task is grading final (and midterm!) exams. I proceed by grading each problem for all students. I really want to know my progress (so I won’t slack off that much), i.e., the number of students I have graded. But the tasks in my case is quite small they should be called micro tasks.
Try it (for fun) at http://theory.cpe.ku.ac.th/~jittat/burnup/ (Note that it has very minimal feature set.)
The code is at github: http://github.com/jittat/micro-burnup/tree
Now I should get back to grading.
