I put the new barometer up on the side of the shed fairly early and then left it for an hour to settle down and I then took a set of readings and fed them in to the new spread sheet I’ve set up using the apple app Numbers. I’ve set a chart for each index.
I’m fairly used to using excel, but I wanted to use numbers. It is (and remains so) a bit of a learning curve, but that’s ok. This all goes back to my desire to have a traditional weather station.
I’ve only recorded one set of data, so no lines yet. I’m not planning to put it on line. I am looking forward to the graphs developing.
