Any chance you can provide a higher quality screenshot? It's hard to see from the current image exactly what the issue is.
If there truly is missing data (i.e. no record for 4/2/18) you'll want to include a row of data in your data set to ensure it is included. You can do that by hand if there aren't too many values or you can create missing data systemically through a cross join. Can Tableau show missing data? — OneNumber
I have put a better screenshot and updated the data with continuous day as in my problem. cheers
With "show missing values" same period can not be separated without having another layer of period.
I could not find recognizable field in your data and added manually added period2.
