Before going on, thanks for this wonderful piece of software.
I’ve been able to plot an histogram using the histogram plugin. So far so good. This is the result:
The histogram works fine because the data is float type rand(0,255), so everything fits in. To construct such an histogram I did the following:
Now my question is whether I could obtain an histogram but that data would be strings. For example, every period of time I do get a string from this vector [“blue”, “red”, “yellow”, “green”].
I tried to get an histogram doing the same as I did with my float-type data, but nothing would be plot.
Is there a way to construct some statistics based on non-numeric values?
I’m using Grafana 4.3.1
