flombone	Posted - 04/24/2013 : 09:40:32 AM Origin Ver. and Service Release: 8 SR5 Operating System: Windows XP Professional Hello everybody, I am trying to write a LabTalk script able to calculate few critical parameters of a large set of data. These represent a lot of S-shaped curves that span from ymin to ymax. I am having problems to calculate the x value for which y gets closer to the mean value (ymax+ymin)/2. Do you have any idea about how to calculate it? Thanks in advance!

JacquelineHe	Posted - 05/03/2013 : 06:28:52 AM Hi, I assume that the X and Y values are in the column 1 and 2. You can try to use this script to get the value: wks.addcol();// add a new column double bb=max(col(2)); double cc=min(col(2)); int aa = wks.ncols; wcol(aa)=abs(col(2)-((bb+cc)/2)); limit wcol(aa); // Find min value in the new column using limit command double dd = col(1)[$(limit.imin)]; // limit.imin -- Corresponding index for minimum Y value. dd=; Please refer to this page about the limit command. http://www.originlab.com/www/helponline/Origin/en/Programming/mergedProjects/LabTalk/LabTalk/Limit_%28command%29.html Thanks, Jacqueline OriginLab
