Removing empty nights from charts?

So I’ve used this for a couple of years but am never completely consistent. I’m focusing on lowering my deficit right now and the days I forget to track throws off the chart completely.
My problem is that I can’t remember those days, so I can’t plot it in.

Is there a way to ignore “empty”/non-tracked nights in your charts?


I have this same need and am hoping for an answer even if it is negative, but of course I am even more hoping for a positive solution.
