how do I store and use fitobjects

For reasons I won't go into I need to store a series of curve fits and plot them all at once.
I calculate a fit to a set of points as follows:
f{i} = fit(x,y,fitModel,fitOptions)
and then plot it using
plot(f{k}, cmap(k,:));
but I get the message
Error using cfit/plot>parseinput (line 328)
Must specify both XDATA and YDATA.
Error in cfit/plot (line 42)
[S1,xdata,ydata,S2,outliers,S3,ptypes,conflev] =
parseinput(alltypes,varargin);
If I look at f{i} , e.g. f{1}:
>> f{1}
ans =
Linear model Poly1:
ans(x) = p1*x + p2
Coefficients (with 95% confidence bounds):
p1 = 92.11 (60.03, 124.2)
p2 = 3.611 (-1.991, 9.212)
If I just do f = fit(x,y,fitModel,fitOptions) and plot(f,cmap(k,:)) it works just fine.
How do I store the curves and then plot them all later in the script?

You could store all the curve fit objects as elements of a cell arrays and then use cellfun to plot all the elements as shown in the following example :
load hahn1
f{1} = fit( temp, thermex, 'rat23' )
f{2} = fit( temp, thermex, 'exp2' )
f{3} = fit( temp, thermex, 'fourier3' )
%%plotting the above curves together %%
figure
hold on
cellfun(@plot,f)
