<div dir="ltr"><div><div><div>Once more I would like to request those who have worked on station data, how the pressure change, weather and clouds should be written. Attached to this mail is a data file I have used. I have tried several ways (trial and error) but I do not manage to plot beyond t, Td and P. Tendency is always plotted as +0 whatever I put there.<br>
