I would like to show density altitude and display an image graph on the weewx html page.
I'm running a raspberry pi with an i2c sensor. I'm guessing the best way would be to have it calculated in software (formula here <https://en.wikipedia.org/wiki/Density_altitude#The_National_Weather_Service_(NWS)_Formula>), how dewpoint is calculated? I just don't understand when and where weewx calculates dewpoint and records it to a database. I do have very little experience debian/python and everything else, so any help would be appreciated!
