Configurable emoticon for "No results"

[wwsean08]

I've been using kibana 4 with logstash and noticed that when there is no data to display it shows a meh face (based on the class in the html). This should not always be the case, one example would be what I use it and that is to look for reoccurring errors in the logs based on the tag. In this case it means there have been no errors in the time frame selected which is a good thing. My proposal to fix this would be to allow one of the view options to say if no data is good or bad (smile, frown, or meh).

For backwards compatability it should be left as meh by default but I would imagine something like the user selects good and it overrides showing a smile, or selects bad and it shows a frown.

Here is a mockup (non-working) of my suggestion:
