Find % of category of the total in a month

[Anonymous]

Power BI newbie here 

I'm trying to calculate Percentage of each category in a given month and display via line graph to show the trend

Data is as below:

Date	ID	Category
1/1/2021	A001	Standard
1/1/2021	A002	Standard
1/1/2021	A003	Emergency
1/4/2021	A004	Emergency
1/5/2021	A005	Standard
1/6/2021	A006	Standard
1/7/2021	A007	Emergency
1/8/2021	A008	Standard
2/1/2021	A009	Standard
2/2/2021	A010	Emergency
2/3/2021	A011	Standard
2/3/2021	A012	Standard
2/3/2021	A013	Emergency
2/6/2021	A014	Standard
2/7/2021	A015	Standard
2/7/2021	A016	Standard
2/9/2021	A017	Emergency
2/10/2021	A018	Standard
3/1/2021	A019	Standard
3/1/2021	A020	Emergency
3/1/2021	A021	Emergency
3/4/2021	A022	Standard
3/6/2021	A023	Emergency
3/6/2021	A024	Standard
3/7/2021	A025	Emergency

What is want to show is for each month (Jan, Feb, March etc..) what is the % of Standard of the total for that month and calculate the same for each month

Hi @Anonymous ,

Check the measure.

Measure = 
var _total = CALCULATE(DISTINCTCOUNT('Table'[ID]),FILTER(ALL('Table'),'Table'[Date].[Month]=SELECTEDVALUE('Table'[Date].[Month])))
var _category = CALCULATE(DISTINCTCOUNT('Table'[ID]),FILTER(ALL('Table'),'Table'[Date].[Month]=SELECTEDVALUE('Table'[Date].[Month])&&'Table'[Category]=SELECTEDVALUE('Table'[Category])))
return
_category/_total

Best Regards,

@Anonymous , Try a new measure like

divide(calculate(count(Table[ID]),filter(Table,Table[Category] = "Standard")),count(Table[ID]))
