Legends in same figure

I am plotting in the same figure from different m-files and I want a legend for each of them to show up, I tried to manage that but I failed.

To make my question clear I called the following m-files,

    Beforefault
    Duringfault
    Afterfault 

 each m-file (Beforefault,Duringfault and Afterfault) has only one figure and the plot part is like this:

   figure(1);
   plot(t,x);
   end

I putted all the three legends in last part of last m-file (Afterfault), it doesn't work.

What doesn't work about it? Does it error out? Does it not have the correct (matching) colors and line styles? Does it not put three (or however many you plotted) lines in the legend box? Can you upload a screenshot to http://snag.gy?

You can delete all of the entries by issuing the "cla reset" command.

I want to keep first entry from the three lines. Can you explain how can I use cla command?

[maro]

I used "cla reset" command it clears all entries before it and this not working for me because I need the first entries of previous plots.

Please anyone have idea can help me.

You can hit alt-printscreen to capture the active window into the clipboard, and then paste into snag.gy.
