You're not getting any responses because it is not clear what you're doing and what the problem is. It will be helpful if you can upload your application.
Meanwhile, just a guess (could be wrong) - look into the "Add-On" in chart properties, go to "Data Handling", and check the box "Include zero values" if it is not checked.
I will give you an example : :
By the way, I have already checked there is no data handling check box issue.
I am selecting a month, April as dimension, There are jonly total 14 dates in the database for April...
I want to calculate daily rate ( My Measure / the number of days). This means the number of days will be 30 for April (not 14)
When I choose more than a month, this total number will be added (For example if I select Apr and May, the number of days will be 30+31=61. This means, daily rate formula = My Measure / 61
I hope that explanation makes myself clear.
Thanks in advance.
