Line graph x axis as each day of a time period

I’ve hit a graphing requirement that I'm not quite sure how to tackle in VA 8.3. I’m hoping someone here can point me to an example or tutorial that covers a similar problem in an efficient manner. I have a data set similar to the following:

RequestID PersonID StartDate EndDate

1 1 1Jan21 10Jan21

2 2 5Jan21 5Feb21

3 1 20Jan21 1Mar21

I’m trying to create a simple line chart where the x axis is each day of the time period 1Jan21-1Mar21 (min value of StartDate through max value of EndDate). The Y axis is the number of people active, meaning people where the day is between StartDate and EndDate.

To accomplish this goal, I’ve been preparing my data by joining the main data set with another table that has a row for each day of my time period on the condition Day between StartDate and EndDate. This greatly increases the size of my dataset from about 6,000 rows to over 500,000 and slows things down. Is there a way to accomplish this in VA without joining the second table?

Thanks for your insight,

David
