fabmsg on Matlab Temperature Distribution

Hi,

I want to make an graph similar to this one that I found on this web site:

https://www.mathworks.com/matlabcentral/fileexchange/56910-thingspeak-weather-station/content/html/ThingSpeakWeatherStation.html

But instead of hourly i wanted to have 3 rows with the Minimum/Maximum/Average  of each month of one year.

I'm new to this and I don't understand this code very well..

thanks for the help!
