When you have multiple data plots in a single graph layer, or in multiple layers in a graph page, you can perform fitting to all of the data plot from Linear Fit or Nonlinear Fit dialogs.
The following video demonstrates linear fit to all data plots in the layer combined as a single dataset. The data are internally combined (concatenated) to perform the fit.
Similar options are available in the Settings Tab of the NLFit tool.
With NLFit, you also have the option of performing Global Fit of multiple data plots with parameter sharing.
