Origin 7.5 SR7
Windows XP

I have a worksheet containing many columns (50-100) of data (Y values) which need to be plotted (against column A - X values) and each fitted to a decaying 1st order exponential in order to extract t1 for each column. Does anyone have a script/macro that would do this automatically?

Hi,

In Origin 7.5, you can use the NLSF object to do that. Some examples are provided too. However, please note that, the document is for the latest version, some features of this object may not work in Origin 7.5. Or you can search this object in the programming help document (select menu Help> Programming).
