Posted - 08/12/2008 : 10:27:11 AM Hi Im using the non Linear CUrve fit tool with the "Expreg1" regression. Is there a way for force the graph to the point (0:0)? like in the linear regression by setting the intercept to 0?

Posted - 08/12/2008 : 1:46:15 PM You will need to use weighting by a dataset. Fill the dataset with 1 except for the point you want the fit curve to go through which can be set very small - say 1E-6 (definitely NOT zero, however). Set the column type as error and plot.
