hello there,
i am having difficulties with the nlsf fit system. i use the understanding code to fit exponential decays to parts of a very long graph.
my problem is that after a while, i reach the 99th fit and then the fitted curves are not displayed anymore on the graph. the fit itself does work.
has anyone any idea on how to expand the number of fitted graphs?
thanks!
nlsf.init();
getnumber (Peak1Begin:) pka1 (Peak1End:) pkb1 (Peak2Begin:) pka2 (Peak2End:) pkb2 (Peak3Begin:) pka3 (Peak3End:) pkb3 [Set Peak coordinates:];
getnumber (Peak4Begin:) pka4 (Peak4End:) pkb4 (Peak5Begin:) pka5 (Peak5End:) pkb5 (Peak6Begin:) pka6 (Peak6End:) pkb6 [Set Peak coordinates:];
//do following 6 times:
nlsf.begin();
nlsf.func$=ExpDec1;
nlsf.cleanupfitdata( ); //begin fitting session
nlsf.p3=5;
nlsf.fitdata$=%(1,@D); //fit first dataset in layer
nlsf.databegin=pka1;
nlsf.dataend=pkb1;
nlsf.tolerance=0; //set tolerance
nlsf.wtype=0;
limit %C;
nlsf.xBegin=limit.xmin; //set up x values
nlsf.xEnd=limit.xmax;
nlsf.xPoints=1000; //number of data points for fitted curve
nlsf.fit(1000);
nlsf.end();

thanks! but is it possible to change the store method to, lets say, 3 numbers aka with max at 999 ???
ciao

This is a limitation in the method that generates the worksheets that store the NLSF data. These worksheets are named NLSF1, NLSF2, etc. all the way up to NLSF99. (These can be viewed in Project Explorer. View:Project Explorer) If you rename some of these worksheets to something other than 'NLSF', Origin will be able to generate more worksheets to hold the data for the fit and you will see fit curves beyond the 99th one.
This issue has been addressed in Origin 7 SR1; so is no longer a limitation.
Thank you.
