Percent of total for bar graph

Hi All,
Despite a lot of googling and looking through this forum, I can’t work the following out:
I have a bar graph which displays the number of patients admitted to the stroke unit per month (pic 1).

I need this to actually display the percentage of admissions to the hospital which end up being admitted to the stroke unit.

I know the calculated field I created is incorrect as it’s now displaying as pic 2.

Can anyone help me with what the script should actually be?

For reference, this is my admissions per month graph:

Thank you.

@jotg - It seems you need to create a calculated field by dividing the 438Treatedinastrokeunit field by the admission field. Something like below and format that as percent

sum(treatedinstrokeunit) / sum(admitted)

Then project that field against the Date Dimension in Line chart. Hope this helps!

@sagmukhe

Thanks.

After some trial and error, rather than sum, it was more appropriate for me to use count.

And if anyone else has a similar query to mine, this is the script I used:

count({438Treatedinastrokeunit})/count(patientrecordid)

My chart now looks like this (which is exactly how I needed it):

.

Thanks again for your help.
