Single stat without a value

This is related to my status page efforts here: https://community.grafana.com/t/grafana-as-a-status-page/22995 to create something like https://status.aws.amazon.com/

Perhaps there is another visualization method that makes more sense (tell me!), until then I am showing a bar with a coloured background whether a query is meeting a threshold. However, I do not want a value to be printed, as you can see here:

I did try making the PromQL boolean for a < 1 but it still prints a number value that I do not want.
