Windows 7 Pro x64 SP1
I have many sheets with TGA data (Mass Loss versus Temperature) and want to calculate the difference between fixed temperature points for each dataset. For example, I need to get a total mass loss at 0-100°C (Mass Loss 1) and 250-600°C (Mass Loss 2) and put the results in a separate table (source sheet name, Mass Loss 1, and Mass Loss 2).
Does Orginin has a handy module(s) for this?
Or the LT is the most straightforward way to follow?
Thank you. |

I have submitted ORG-21998, so we will see, basically to add a system variable to indicate that label row area is not going to be output of any recalculation.

Is there a way that you can avoid that?

I see the point.
My idea is to design a summary sheet that would collect the required information from the other sheets. Essential places for the target data coordinates are Columns' Label Rows. Therefore I don't see a good way to avoid this.
Is there an option to disable the cyclic reference prevention for a selected sheet?

Can you reproduce this?

As for Auto Update, as long as Recalculate is Auto, then it will auto update.

Got it. Thank you.
As for Auto Update: it works only if I clear formula cell and re-enter it again:
How do I achieve Auto Update if I change the values in Column Label Rows? |

You can specify user-defined label rows that way. For more information related to label rows, see: https://www.originlab.com/doc/LabTalk/ref/Column-Label-Row-Characters

Thank you for sharing this!
What does (1,2) mean in the %(wcol(j)[Sheet]$)!(1,2)?
Where can I read about this syntax?
Also, how do I force automatic update of the set Column Values? |

Hi,
See the illustration below for one good method to achieve what you want.

What column formula I should use to populate the table with interpolated values based on X from column A and sheet names from column label row "Sheet"?
Thank you. |

We can prepare a blog on this, but can you see if this is useful?

Hm...
Sounds interesting.
Can you share a good example of column formula acting over different sheets in the specified workbook, please? |
