How to plot a line generated by Curve fitting tool?

I plotted all my data on a Matlab graph using the "Plot" command.

Now I want to display the curve generated by Curve fitting tool and superimpose it on my plotted graph.

After saving the fit, there was a new variable (1x1 Cfit) named fittedmodel. How do I use that to plot a line so as to see how the line divides my data?

I know the app makes an Image of the data with line, but that data characters are not colores. So is there any way to extract the equation out of the app and plot it to my graph?

TIA

You can save the cfit object, statistics and fit output directly..

Or, having saved the object, just use it as argument to plot--it's overloaded to handle the object...

Agree the doc for the tool are kinda' hard to follow with all links
