Value and Percentage in Bar Graph

Hi All,

I'm trying to create a stacked bar graph which displays both values and the percentage within the same graph. The only problem is that I don't want the percentage to be of the "Grand total" like the option power bi gives if you select the "show value as" option, but I rather want the percentage value to reflect the percentage within the total value of the stacked bar. The data being represented below is the amount of tickets a support centre receives each day and it is being grouped into months. The ticket are categorised as either inside SLA or outside (which is seen in the legend). 

Can anyone please help? Thanks in advance!
