Average tags

A new project I started modifying the history table in wxlocal14 to suit my needs
I can not find these tags I need

average wind last 24 hours
average year to date barometer
Average year to date humidity

https://weather.scottsworld.info/details.html

average barometer over a year would not be very usefull I would have thought
if you set up a data base, e.g mysql
then you can use that to create anything you like

I have tried to set up msql a couple times, I says it is missing some component I cant find, dont remeber what it was. Know I had to install Ruby for it

I could add average wind speed last 24 hours easy enough
average barometer over a year will likely just be just the average 1013hpa I would suggest?
