plotting three curves in the same plot

I have plotted the follwing two curves as in the image below (fig2).

For the curve in red I have used a matlab generated code to do some curve fitting for it and got the curve in the below image (fig1).

Now I would like to be able to add the fitted curve to the plot in fig2 for comparison reasons, is there a way to do that?

thank you in advance,

YEs, you can plot. Read about hold on

[Sajid Afaque]

yeah you can use hold on before curve fitting

or

alternatively

figure(2); %the intended figure number on which you need plot
hold on
plot("your data")

[Sajid Afaque]

your this line is creating a new figure

figure( 'Name', 'untitled fit 1' );

hence you are not able to get the plot on the same figure

i can no longer see your comment (why did you delete it)

you can also use this

%in the first section
fh = figure;
ax= axes('Parent',fh);
hold(ax,'on');
%then your two plots
plot(ax,'plot 1')
plot(ax,'plot 2')

%% then you can apply optimisation 
%and now the fitted plot

plot(ax,'plot 3')
fh.Name = 'khan 1'; %you can name your figure
