Origin Ver. and Service Release: 7.5 RS6
Operating System: Win7

I have some data I'm trying to fit with multiple gaussian peaks. The shape of the data is most conducive to using between 3-5 peaks. However, when using the NLSF tool I find that if the auto-fitting system chokes on its initial run (the one run between the "Weighting" and "Fitting control" sections) the plot it generates cuts off above an arbitrary x-value. I've included a screencap.

I have no idea how to mitigate this. Deleting the plot I was fitting from and re-plotting the data does not work. Nor does re-scaling the working plot within the NLSF module. I'm at a loss! Is this a bug?
