In cumulative count zero replacing with previous value in line graph

My problem is, I want replace zero with previous cumulative count. Is it possible?

For example at 19th march no data added so the graph show value zero but I want 1626 here (which is value of previous date i.e 18th march )

Can you please suggest something to solve my problem.

Hi @varnika
It looks like you don't have any data for when the number is zero, and you have set "Replace missing values with"="Zero" - try using "Linear interpolated" instead.
If you need a dot for each date, then your results needs to return that.
