I have a range of data in my Excel 97 spreadsheet existing of a column with dates and time and a second column with pressure values. This data has to be analysed on when it passes zero.
What I have to do is to count every time the pressure value comes below zero and how long it takes to rise above zero again.
Can someone give me some help with this ?
tnx.
Bert.
