Origin Ver. and Service Release (Select Help-->About Origin): 8SR6
Operating System: WinXP

Hi,

I have many curves to fit and I like the new NLFit dialog and the
resulting parameter sheet added to original worksheetpage. I wonder
whether there is a way to access this from OriginC such that I get the
plotted curve to the graph windows as well as the parameter sheet.
As far as I understood the NLFitSession class does not provide access to
this.

Best regards,

Sven Friedemann

Dear Iris,

thanks very much for the help, it did what I wanted.
However, there is only one question remaining.
Is it possible to access the resulting parameters from trOp, the operation tree? Right now I only accessed them via wks.GetReportTree.

Furthermore, you asked for some user story. It is quite simple. I have several sets of data to which I perform a linear fit and extract the slope to a summarizing worksheet. I only would like to have a look at the performance of the fitting in order to exclude bad data points from the fitting.

Best wishes,

Sven

Hi Sven,

I updated Fit on Multiple Datasets with Parameter Shared to add code to show how to access parameter values by operation tree. Please look at "// output parameter values" part.

Thanks,
Iris
