@Ray @Mark: I don't know where they get the values from but I think I do understand some reasoning behind it. In CUtils I use the maximum and minimum values of the barometer ever measured on the station for the scale. The idea is that if you see more than one day you see the barometer fall/rise if a depression comes over much like a real barometer would show you. The values used by Wow are almost like mine : 1050 and 940. So maybe you check your max/min values (record values) of your station. My guess is that they are close by the values Wow uses.RayProudfoot wrote: ↑Thu 10 Apr 2025 9:02 am Is anyone else frustrated with the graphs produced by WOW software? Why don’t they use some intelligence with the scaling? To have a base of 920hPa and a peak of 1040 is ridiculous. I’d be embarrassed if I produced software of this quality.
I cannot see any way of reducing the vertical scale of 120hPa. Can anyone else? It makes generating graphs pointless.

Re: Met Office WOW uploads
@HansR, my all-time pressure records are 962 and 1048. It doesn’t appear the Met Office are using those. I think they’re fixed.
For those of you who have created charts in Excel the software is intelligent enough to determine the min / max from the data. Seems those at the MO haven’t bothered. I did hope that part of this exercise might have improved the charts. It hasn’t. Hence why I use Access and Excel to generate my own.

Re: Met Office WOW uploads
To be honest I rarely look at WOW, I update it because it is the UKMO and I like supporting the UK. I hope they may find the data useful. I saw little point in sending data out of country especially to the USA right now
.
The only reason I send my data to Ecowitt currently is for filling in missed data but when my GW3000 is stable enough with the SD card that will stop as well!

Same here Stuart. Just a little disappointing they don’t provide better analysis tools.broadstairs wrote: ↑Thu 10 Apr 2025 3:12 pm To be honest I rarely look at WOW, I update it because it is the UKMO and I like supporting the UK. I hope they may find the data useful.
