Hi,
I am running LibreOffice 5.4.6.2 and am using a spreadsheet to enable me
to draw graphs based on rainfall received per year, up until the date
prior to today. The figures also allow me to compare current rainfall to
date to the same period in a previous year. I agree I should probably
use Base but I do not think it would have solved the issue.
**Example Data***,,,,,
Month,Day,M/D,2016,2017,2018,Average('16->'17)
Apr,1.04/01,3,0,1,1.5
Apr,2,04/02,0,8,0,4
,,,,,,
,,,,,,
,,,,,,
Apr,26,04/26,0,0,20,0
Assuming today is Apr 2nd, a formula to count how many days of rain
there were in the current month would be =COUNTIF($F$2:$F2,">0"). The
Total amount of rain that fell on that number of days, being 1, was 1mm,
or taking it further 60% of the average rainfall to date for the month.
Assuming today is Apr 27, a formula to count how many days of rain there
were in the current month is unknown, especially as there are
undoubtedly values in the other un-shown 81 cells i.e. 3yrs and 27
remaining days?
Basically take the starting cell reference $F$2 and add the number of
events that were ">0" to get the end reference for the COUNTIF formula.
=COUNTIF($F$2:Add number of items ">0" to the starting line reference 2,
to get the end of the COUNTIF range) i.e. being Apr 27, whilst there may
be 26 days between the beginning of Apr and today i.e. Today()-1, there
are only two instances in the above table where ">0" for a particular
year, thus making 2 the number of days it rained, to receive the SUM of
the 2018 rainfall being 21mm
I have Googled silly but my GFu is lacking something as the solution
evades me, even after reading the LibreOffice help files.
For reference the formula to count the number of days from 1st Apr to
Yesterday:
=DAYS(TODAY(),"2018-04-01")
I have uploaded the file to
<https://drive.google.com/file/d/1tnwBOvl2QTYeS4wkMQlg63J9oTK_UxOw/view?usp=sharing>
for folk to view. quite willing to upload the spreadsheet
I will need to re-write at least 36 formulae being one for each month of
three years, but then hopefully I can leave column AC and concentrate on
entering the data correctly and optimising the graphs.
Ideally I think I need a formula to give me the number of days between
$F$2 and 'TODAY() -1' and add that number to the cell reference to
create the end of the COUNTIF range.
I hope you can point me in a direction that will help.
Regards
Hylton
