I want to fit 7 curves simultaneously using the one given equation (of course, different parameters). After fitting, I will visulize these 7 curves in the same graph. So the 7 curves need to be set in different colors except red. And the fitting curve needs to be set at red.
Is this visualization possible? If so, how?
Thanks.

I got it. Here we go:
With your graph active, open the NLFit dialog, by selecting Analysis:Fitting:Nonlinear Curve Fit.
On the Data Selection Settings tab, the InputData node will have a Range defined for each curve in the active layer of the graph. To Add or Remove datasets as well as edit each Range, use the Dataset Browser dialog, opened by clicking this button, .
To fit all curves in all layers of the graph, click the arrow, , next to the InputData node and choose Add all plots in active page--- This is the key point.
Thank you all though.
