Re: [hobbit] NCV Graph not showing up

["Gary B." <gmbfly98 (at) gmail.com>]

Try replacing "roomtemp" in hobbitserver.cfg with "Temperature".  I'm not
sure if that makes a difference or not, though.  Also, make sure the script
doesn't generate any other text besides "Temperature: <value>"...  I had a
script that output some non-value text before the actual text, which was
causing NCV to try to parse that into a number (and thus "NaN" - Not a
Number).
