The problem I am running into is that the fit always replaces the original plot and I can't seem to get them to both show up. By the end of the fitting the orignal data curve has always been replaced and I can't seem to add it after the fact to the plot. I appreciate any suggestions The code is below: vector fitter(Curve temp_data, int downRange, int upRange, string func) { //pass to this function the curve to be fit with the range and the fitting function and it will return //creates a visible plot GraphPage TET; //Graphs results of fits GraphLayer TOT; DataPlot TAT; vector params(10); string data_name; using NLSF = LabTalk.NLSF; //NLSF is the fitting engine NLSF.Init(); // initialize fitter NLSF.PasteToPlot = 1; // turn off pasting results to graph NLSF.Func$ = func; // assign fitting function NLSF.numReplica=0; temp_data.GetName(data_name); TET.Create(NULL, CREATE_TEMP); TOT=TET.Layers(0); set_active_layer(TOT); TOT.AddPlot(temp_data); TAT=TOT.DataPlots(0); TOT.Rescale(); TET.Rename(temp_data.GetName()); TAT.SetRange(downRange,upRange); //Sets the range of the fitting NLSF.begin(); NLSF.cleanUpFitData(); NLSF.msgPrompt=0; NLSF.FitData$ = data_name; // assign fitting dataset NLSF.dataBegin=downRange; NLSF.dataEnd=upRange; NLSF.Execute("parainit"); // perform auto parameter initialization NLSF.Fit(300); // perform fit params[0]=NLSF.P1; params[1]=NLSF.P2; params[2]=NLSF.P3; NLSF.pasteParams("P"); NLSF.end(13); NLSF.unInit(); // TET.Show(FALSE); TET.Detach(); return params; } [/quote]   Check here to include your profile signature.
