Gauge Thresholds

Hi Guys,
I am new to Grafana and am having an issue with one gauge where it does not seem to trigger the thresholds.
I have set the threshold to 20,50 and the percentage used is 54 so I am expecting to see the text go yellow, but no matter how i configure the thresholds i cannot get it to trigger.
Any help in pointing me in the right direction to start troubleshooting would be great.


Can you show a screenshot of the Options tab? And can you show the raw query and data. Here is a guide on how to get that from the Chrome Developer Tools.
