Hi! I have a figure with multi lines plotted in different steps. plot(a); hold on; plot(b); plot(c); plot(d);
I want to clear only the some of the plots and hold the rest.
delete plot(a) and plot(c)
cfl will remove all. Any solution to this? thanks.

figure
hold on
h1 = plot(rand(10,1)) ;
h2 = plot(rand(10,1)) ;
h3 = plot(rand(10,1)) ;
h4 = plot(rand(10,1)) ;
set(h2,'Visible','off')
set(h4,'Visible','off')

This does not clear them from the plot, just makes the lines not visible.

This will actually delete the line objects from the axes:
ah = plot(...);
hold on
bh = plot(...);
ch = plot(...);
delete(ah)
delete(ch)
