Here's a derivative of an another plunk:

The only change I made was to set the February red point to zero. The marker there is clipped and you only see half the circle.
I read old threads on setting margins, turning off clipping etc but none of those worked for me. Can someone provide a change to the above plunk that shows how to get that marker to show in full?
