How is barometric trend set?

I have noticed that summary.gif and station.html produced by WD show differing barometric trends. For example the gif file can show a rising arrow whereas the table produced by html can read steady or falling.

Is there supposed to be a relationship between the two? I would expect that they would both show the same trend.

i will have to check the code…
but are they both produced at the same time?

The quick answer is yes.

here is screen shot that shows what I refer to .

I saw the previous thread in 2004 but as the pressure is recorded in whole numbers I cannot use a decimal of hPa.

Did you get a chance to look into this as discrepancy continues?
