Origin Version (Select Help-->About Origin): 7.5
Operating System: XP
I am new to using Origin and am not sure the best way to even approach my problem. I am fitting data from multiple experiments (around 10 data runs per experiment) and I would like to track how peaks shift. I have used the peak fitting module to fit my data nicely and generated lots of different reports from these fits. The problem is that I have different worksheets for each fit and I really want to compare individual peaks.
Should I be trying to combine all the different fits onto one worksheet (and can I use append to do that with some c code?) Would it be easier to try to plot peak positions using data from different worksheets (and again, is that done with a c code?) or is there some other way I should attack this problem. I have no experience with writing in origin c, but I'm willing to try new things. I figured it would be best to ask for advice first since I don't know all the things the system is capable of.
Thanks!

Hi Jenniferr:
You may or may not need to program depending upon what you envision for an end result. A simple LabTalk script could probably be written that gathered all relevant data and put it into a new worksheet and, from that, you created a single plot (it could be something like this, maybe?? http://www.originlab.com/index.aspx?s=9&lm=153&pid=985).
Or, the solution might be as simple as using the Merge button on the Graph toolbar to merge all open graphs in the project onto a single page -- either as separate panels or superimposed on a common scale/set of axes.

Thanks for your suggestions! I'm not quite looking to combine different plots, because really there is just one parameter from each fit (say the central position of one peak) that I would like to track over multiple fits. So, I need one cell from 10 different worksheets to be plotted together.

Hi Jennifer,
There are others who would be better able to advise you as to what you might want to do, but I will point out that there is a section in the back of the Peak Fitting Module Manual on "Programming the PFM with LabTalk." Note, for instance, that there is a post-fit property pf.centern that returns the center of the nth peak.
I'm guessing that you would like to collate results from a lot of analyses, and that any automation of the process would simplify things. If that is the case, you will probably want to study the PFM Manual (and the LabTalk section of the Programming Help file) and sketch out a process that will lead to the desired end result. There is a separate LabTalk forum here, where you can get help with specific LabTalk questions. Alternately, if programming this seems a bit overwhelming to you, you might want to contact OriginLab's consulting group for help with your project.
I hope that this helps you a bit.
