Display Total Value on Stacked Bar Charts

Hi Alex, Thank you so much for reply.

I have had a look at it before but was not sure about layout in JSON, which i tried as per you mentioned and it works quite good but when i hard code the values in annotations.

But i have date picker which can vary over multiple months (1 month = 1 bar) and also Multi-select component to allow user to filter down categories(stacks). Can't seem to figure out how should i tackle it.
