Origin Ver. and Service Release (Select Help-->About Origin): Origin 2020 (64-bit) SR1
Operating System:W10
Dear all,
I am very new to Origin, so please indulge me if the answer to this question is too evident.
For a large datalogging csv file, we found that one of the queries was not constantly giving the value for each timestamp if there wasn´t any change (discrete numerical values). That led to have many blanks randomly distributed through the affected columns in a file with more than 80k rows. I would like then to "replenish" them for some posterior filtering, correlations, etc.
Despite my first attempt to find a "how-to" either in the forum and/or in the web, I didn´t succeed. Therefore I will be very happy for some guidance with this issue.
Regards,
R. |

The B[i-1] notation needs a newer version. I checked it didnt work in 2020, 2020b, but it worked in 2021 at least. Best if you download the latest version, which is 2021b.
if(isNa(B),B[i-1],B)
or
isNa(B)? B[i-1] : B
to avoid the comma issue.

Hello Snow,
I actually tried already and it is even worse: it crashes Origin :(,
the thing is that I even changed the settings in windows and this behavior continues..... |

Hello, for German Origin, comma may be used as decimal separator.
So could you use ; instead of , between arguments in function.
E.g. if(B==0/0; B[i-1]; B)
Thanks, Snow

Dear Shirley,
thanks a lot for the prompt reply. I could only sit back on this topic and I tried your solution. However the outcome is not clear to me. Basically when I hit apply, the software automatically changes the "," to "." and instead of filling the missing values with the former in the column, it just simply fill all of them with "1". I have attached a couple of screenshots to illustrate this issue in order to find out what I´m still doing wrong.
Looking forward to hear from you, |

Hi Raul_V,
If you want to fill the empty cell with the previous values above the cell, you can try to use Set Column Values tool with the formula below:

Please let me know if you have any problem with this solution.
Thanks,
