5.The “0h” on the horizontal axis indicates the current hour, thus the current air pressure also.
6.Each bar on the bar graph represents a value of 0.03 hPa, and each bar also has a corresponding value on the verticle axis.
7.Air pressure trends can be determined by simply glancing at the bar graph.
a.If the bars are rising (higher on the right than the left) then the air pressure has a rising trend, and the weather should improve.
b.If the bars are dropping (lower on the right than the left) then the air pressure has a falling trend, and the weather should worsen.
8.Multiply the two values to find past air pressure (note the + or – sign of values on the verticle axis); i.e. 0.03 hPa x 3 = 0.09 hPa, now add this value to the air pressure (in LCD 4) to evaluate what past air pressures have been.
9.The bar chart will constantly scroll to avoid burnout of the LCD.
