How did you create the plot? If I use
fp=fit(x,y,'poly1');
plot(fp)
I don't get anything but the line.
But, use the optional line spec when you use plot with the fit object or save the handles to the lines and set the linestyle afterwards.

This works for me! How would you go about plotting fp1 and fp2 on the sam graph? I keep getting this?
>> plot(fp, fp1)
Error using cfit/plot>parseinput (line 335)
Must specify both XDATA and YDATA.
Error in cfit/plot (line 42)
[S1,xdata,ydata,S2,outliers,S3,ptypes,conflev] = parseinput(alltypes,varargin);
>> plot(fp fp1)
plot(fp fp1)
↑
Error: Unexpected MATLAB expression.

Only one fit object can be specified in the augmented plot routine. Use
plot(fp)
hold on
plot(fp1)
...
to add to the existing axis just as with any other plot/axis...
