How to implement Stacked Bar Charts to show monthly Counts within each of the stacks? I've noticed that it is a requirement to provide counts for all the months (stacks) for each of the bars, to generate a valid stacked chart. This results in an issue that if the count/total for any month is 0, that stack appears with 0 height and the number 0 is also shown. So if a couple of months have 0 counts, all the 0s overlap with each other and they also overlap with the count of the first stack that has a count greater than 0.
