A rising graph generally means improving weather.
A falling graph generally means deteriorating weather.
Note that if there are sudden changes in weather or
temperature, the graph line of past measurements may run
off the top or bottom of the display. The entire graph will
become visible once barometric conditions stabilize.
The following conditions cause the barometric pressure
measurement to be skipped, with the corresponding point on
the barometric pressure graph being left blank.
• Barometric reading that is out of range (260 hPa/mb to 1,100 hPa/mb)
• Sensor malfunction
