Error when field data circuit breaker hit

[jimmyjones2]

Got a dashboard with a pie and a data histogram. Because I've not been using doc_values and I've been aggregating everything in sight, I've hit the field data circuit breaker. However I do still get the pie, but where the histogram should be is completely blank and I get an error in the javascript console:

TypeError: Cannot read property 'values' of undefined
  at http://localhost:5601/index.js?_b=5028:37405:22

Looking into the response from ES, it send the two queries, but one came back as failed due to the circuit breaker. Maybe give the user a visible error?

Same error when I've fixed my circuit breaker issue, looks as if its #2428 again which needs to be reopened.
