Doughnut chart second layer

Hi,

I am trying to do something - I have plotted the months with their respective lengths (of course differences are almost invisible to ***** eye) on doughnut chart. Is there a clever way to get a second layer to doughnut chart that shows individual daily units for each month. I want to use this for to visualize annual deliveries, i.e. add tasks and deliveries on the specific place on the doughnut chart, i.e. if delivery is on 31st of January, I want to point an arrow from that specific area for January and add a task name. If there are any other clever suggestions, please (do not suggest Gantt chart please ).

Thanks in advance

Hi,

It actually does the job. Big thanks! It is approximation only and I can only turn on data series name separately for those units that I need.

best regards
