How can I perform multiple linear curvefittings in a single plot?
I would like to have all fitted lines in one plot but I also need all parameters as calculated for each line.
Can that be done in Origin? |

Hi Paul,
I'm not sure which version of Origin you are using, but starting with Origin v. 6.X one can fit multiple curves in one plot (and in the same layer) using the Linear Fit tool. Simply choose Tools:Linear Fit. In the Settings tab select 'Fit All Curves' then execute your linear fit.
In Origin versions 4.X and 5.X you would need to activate each dataset in the layer before performing the linear fit. After you do your initial fit, choose the Data menu option. You will notice in the drop down menu a checkmark next to the active dataset to which the linear fit was just executed. Select the next dataset in the Data menu. If you choose the Data menu option again, you will notice a checkmark by the next dataset you just selected. Run your linear fit again. Choose the next dataset and so on.
