This sounds quite stupid.

I usually got data from json like  
{ "name":"john","category":"A"}  
{ "name":"paul","category":"B"}  
{ "name":"henry","category":"A"}  
{"name:"jane","category":"C"}  
I easily manage to get the percentage of category A and percentage of category B in a pie chart with an index made of two fields : name and category.

My problem is that I now have a json that comes with the percentage being already processed. something like :  
{"categoryA":50}  
{"categoryB":25}  
{"categoryC":25}  
My index is therefore made of 3 fields : categoryA, category B, categoryC  
How do I make a pie chart that will take into account the categories value?

I should be so simple and I don't see how.

Thanks for your help

You can use `top hits` metric to use a value from the document as the pie slice percentage

In the screen shot below, the pie slice percentage is from the `hour_of_day` field for the first matching document for each split.

That means i would have to change a bit the structure of the json I receive, so that I get something like this :  
{"category":"A","percentage":50}  
{"category":"B","percentage":25}  
{"category":"C","percentage":25}

Thanks.
