How to convert this chart into percentage

[Anonymous]

I have one chart that gets number from table and the other from another table.

I want to subtract those two numbers and show it as percentage then...

Lets use this as an example

The total is 181 (we have this figure)

We have the point 1 being 156 coming from table

we need to take percent of point 1(156) and

the second one we got which is point2 (25) we got this by subtracting the total 181 from point1(156)=25

I want to show the percentages which are

Point 1 : 86%-181

Point 2: 14% -25

in pie chart format

how can i

hope this is clear
