Other basic examples

I invite you to go to the Basic fitting mode and try to recover each Basic-1,2,3,4,5 examples and study them. I think they are self explainatory.

I would like to point to you that if your function can be written as the sum of different functions like in

\begin{displaymath}
y=y=f_1(p_1,p_2,...,p_n,x)+f_2(p_1,p_2,...,p_n,x)+...
\end{displaymath} (1)

you have the possibility to produce plots where each function $f_1$, $f_2$,... is represented by lines of your choosing. In order to obtain this you write the following
\begin{displaymath}
y=a \mbox{$\backslash$+} bx
\end{displaymath} (2)

as your function and compile it.

Fig. 10 was produced after selecting dashed and dot dashed curves in red and green colors for the two components in the plot menu.
