Hi everyone.
I'm havin a rather simple problem by analising some data, and you can probably help me.
I've done some measurements of braking times and got some curves I have to compare. The problem is that the brake time is different for every measure. Some curves are 60s long and some just 10s.
I was planning stretch the curve to the lenght of the longest (60s) and then compare them. I know that I'm going to lose the time-information, but this is not important. I need just the Y values of the curve.
The problem is that I havent found a function in Origin to do this. The only function I found was NORMALIZE, but ist normalizes the data in Y, and not the X-data...
Is there an easy way to do this?
Do you have some advice for me?
Thank you!!!!!

Hi Claudio,
Say the shorter measurement is in cols 1,2 of a worksheet.
You can then make that worksheet active and bring up the Script Window (menu item Window|Script Window) and type the following command and press Enter key:
col(1) *= 6
This will scale x col by 6.
You could do linear transformation such as
col(1) = 1.5 + col(1) * 6
etc
