Barographs

I like the barograph on the meteogram .
It would be useful to me to be able to draw the forecast air pressure at two different sites .

The trend in the pressure difference gives a target pressure for when the two traces cross , and that can be used as a parameter in the real world (barometers are also on the mobile phone) for impending wind changes. ... more accurate than the model wind forecasts.

Thank you for the idea. It would be quite complicated — combining data for two locations at once is a rather complex task, especially distinguishing which data belongs to which one.
