Hi everyone,

I plot twice in one figure by using the hold on, but I find my 2nd plot is wrong. So I have to delete the 2nd plot, but I don't want delete the 1st one nor do I want to plot them again. Is there any methods?

Thanks a lot~~~

This thread might help (If you have plotted the two separately ) http://www.mathworks.com/matlabcentral/answers/1444-clear-one-plot-in-multiple-hold-figure

h1=plot(1:4)
hold on
h2=plot(2:8)
delete(h2)

Or use the findobj to find the second plot and delete it.

doc finobj

Is there a way to bring back a signal after deleting it? or if we can use plot/unplot all the signals in the plot by using something like a check mark?

(just to avoid a double thread with the same question, I replied in the other thread this was posted)

Click "edit plot" -- the arrow next to the printer icon.

Then, click on the line you want to delete and then delete it.

Another way, is to click on the line you want to delete and then with that line selected.

 >> h = gco;
 >> delete(h)

As in on the menu bar with : " File Edit View Insert Tools Desktop Window Help"

That edit?

Doesn't seem to work.

@Orion Smedley: "Edit Plot" is the first item under the "Tools" menu.

Wayne King was saying how to access it from the toolbar. It's a white arrow/pointer, and it's located in different places in different MATLAB versions.
