Matlab sub-plotting with curve fitting

Hello,
I have created subplots and I am attempting fit a linear curve to each of the subplots. However, matlab only allows me to fit a curve to one plot and when I try to fit a curve to the second curve, the curve on the first disappears. The version of matlab I have is R2010a.
Can anyone help?
Thanks in advance

Curve fitting has nothing to do with sub-plotting. I am not sure if you are using subplot() or you mean different curves in the same axes.
If you want to plot multiple curves in the same axes, you can use "hold on". If you use subplot(), you can use axes(h) to activate whatever axes you choose to work on.
Showing your code would be the best way to explain the problem.

I think the problem is when you use the fitting tool to draw fitting line after the subplot is created. The tool allows to select a particular data and then draws the fitting line but the previous fitting line is cleared. So you can see only one fitting line. It also says in the toolbox help.
Solution: Create a fitting for one graph and then generate the code and use the generated function to fit on sub plots.
