Field chart for non-numerical fields breaks

[lennartkoopmann]

When creating a field chart for a non-numerical field you should get an error message explaining that you can only build field charts from fields with a numeric type. This was the case in pre-v1.2.2 versions.

In v1.2.2 I am getting the loading spinner forever and this JS error message in the console:

Uncaught TypeError: Cannot read property 'x' of undefined

Google Chome Version 46.0.2490.80 (64-bit) on OSX 10.11 (El Capitan).

Update: This only happens when I am searching over All messages and not if I search over last 5 minutes. Is this related to ES failing and us not catching the error?
