How to get cumulative percentage with date filter on stacked column chart

[Sharma0815]

I am working on a dataset where i need percentage of each category of surveys and I am using stacked bar chart to visualize the data 

I have date range filter, when i change date range to one particular month percentage the bar chart is not showing like i expected that means it's not 100% cumulative

For example ,

responseid	category	date
1nflkjnsldkn	Top2	1/1/2020
23dffthrghf	Bottom2	1/2/2020
sdgfgdfgdfg	middle2	1/3/2020
sdasgasdgg	Top2	1/4/2020
dfdgfhadvv	Bottom2	1/5/2020
cvbghrttsd	Top2	1/6/2020

I have survey responses from 06/01/2019 to 06/012020 and I am using below DAX to caluclate the percentage 

TotalSurveys = DISTINCTCOUNT(Survey[responseid])

%ofCategory = DIVIDE([TotalSurveys],CALCULATE(DISTINCTCOUNT(Survey[responseid]),ALLSELECTED(Survey))) 

I am placing caterogy on legend and it's working as I expected if i select date range for all months.

I want to visualize the percentage of survey by category if i change my date filter to one month.

For example ..in the below screenshot I've 323 surveys in Jan 2020 and i want to visualize %of surveys by category with cumulative of 100%

Total surveys 3200 from Jun19 to Jun20there are 323 survey in Jan 2020

Is there any way that we can achieve this by using DAX ?

Do you have survey data for each of the categories in each of the months?  if yes then you can do a simple cumulative count against your dates table. If no then you need to use CROSSFILTER(survey date,dates date, none) to fill in the gaps.
