YTD calculations or Running Sum

[Patv]

Hello Friends/experts, 

I have a requirement to create a Bar/Line chart with like Active projects per month.  and I have created  three measures to do so..

1. VAR_NUMBER_PROJECTS_CREATED = CALCULATE(COUNT(GP_PROJ_JEP_OPEN_CLOSE_COUNT_V[REQUEST_ID]),FILTER(GP_PROJ_JEP_OPEN_CLOSE_COUNT_V,GP_PROJ_JEP_OPEN_CLOSE_COUNT_V[CATEGORY]="GeneralProjects_Created"))

2. VAR_NUMBER_PROJECTS_CLOSED = CALCULATE(COUNT(GP_PROJ_JEP_OPEN_CLOSE_COUNT_V[REQUEST_ID]),FILTER(GP_PROJ_JEP_OPEN_CLOSE_COUNT_V,GP_PROJ_JEP_OPEN_CLOSE_COUNT_V[CATEGORY]="GeneralProjects_Closed"))

3. VAR_ACTIVE_PROJECTS_GOOD =

[VAR_NUMBER_PROJECTS_CREATED] - [VAR_NUMBER_PROJECTS_CLOSED]

if you see the line in  below chart ( attached), there are 17 PMATT projects for April 2022, 8 PMATT projects in May 2022 , 3 pmatt projects in June 2022, etc... 

My requirement is to show PMATT projects like below..    

for April 2022 = 17

for May 2022 = 25 ( 17+8)

for June 2022 = 28 (17+8+3)

for July 2022 = 36 ( 17+8+3+7) 

etc...

How do I achive it?  please send me formulas if possible so I can understand it .Thank you so much.!
