Hi,  
I want to calculate the percentage of each bucket regarding the total value. as an example;  
let's assume we have sale per month calculated (for a couple of months) as follows:  
month1 -\> 10  
month2 -\> 25  
month3 -\> 15

I want to have the percentage of months too:  
month1 -\> 20%  
month2 -\> 50%  
month3 -\> 30%

I've tried bucket\_script but as it is a parent pipeline aggregation I cannot have access to the total value and what I have access to is the statistics of that individual bucket.

Is there any way to pass the total value inside bucket\_script?

Thanks in advance
