Percent Total for each month

Hello,

I would like to caculate the percent total of jobs with a JobTimeSpan equal to or below 24 per month. Ideally I want to use a column chart with Month-Year on x axis with %total as the y-axis. I am using the below measures but it calculates the % of all months rather than each individual month. 

Total Jobs: COUNTA(Request Name)

All Jobs: CALCULATE([Total Jobs], ALLSELECTED(Jobs)

%Total: DIVIDE([Total Jobs], [All Jobs], 0)

For example, on the matrix above how can I get each month's total to show as 100% instead? 

Thank you in advance!
