There is now little more than a year since I began to read every day at 14:00 local time clock at the airport, the meteorological data and save it. Last year I ever had a graphic with the heat index published here. Now after a year I would like to display the following graphics:
first Real measured temperature ° C
second Relative humidity in%
third The resulting heat index calculated in ° C
missing total, only about 4 days in December 2008 when I was on vacation no way to retrieve the data.
