I tried but was unable to reproduce this error on my computer using my own datasets and graph windows. In order to understand, diagnose, and make recommendations for a problem of this nature I need to be able to reliably reproduce the problem so that I can analyze it while it is happening.

Please contact your Origin dealer's Technical Support department by email describing this problem in detail. In the email you should include a list of steps that you follow to reproduce the problem and a listing of all relevant settings in the Linear Fit tool. You should also attach a sample project that contains a graph window where the error occurs. A second graph window where the error does not occur would also be helpful. This type of information is essential for problem solving.

I am quite sure that if provided the information described above your Origin dealer's Technical Support department will be able to resolve this issue. Don't forget to include a registered serial number along with your request for assistance.

Thanks...
