Hi my friends I'm very new on kibana. I want to create a pie chart with a field who contains a list, like this:

[passed, passed, passed, passed, failed, failed, failed, passed, passed, passed, passed, passed, passed, passed, failed, passed, passed, failed, passed, passed, passed, passed, passed, passed]

When I create the pie chart I get a 50/50 percentage that is wrong because in this hit on this field there are 19 passed and 5 failed like the list above. I am slice by the field that contains the list and size by count of record. I am not sure what I am doing wrong. Please help.
