Sometimes a big task requires many small steps to be completed. When planning, I split it into such steps that are clear how to complete in short time intervals. Timing each step may bring good dynamics into work, and sometimes signals that a step should be further divided. I was curious to see a visual representation of actual time intervals to complete a recent sequence of such steps.
A simple bar histogram seemed sufficient to satisfy this curiosity. Matplotlib Python library was helpful as always. Some insight could be gained even from such a simple visualization. For instance, in that particular task, after some time, steps were taking longer (maybe it was a natural point to take a break? or may be a point to re-plan the further steps?).
The code of this example is available at github.
