I have plotted a graph and generated a fitting with MATLAB curve fitting app.
When i use plot(fittedmodel), the curve fit goes to infinity. I would like to set a range on which the fitting curve will be plotted.

Instead of using plot() of the fit object, use linspace() to generate a range of x values, and pass the range into the fit object
MyFitResult = fit(....);
x = linspace(0, 2.2);
y = MyFitResult(x) ;
plot(x, y)
