I need a hand with some graph function... :O

Is there a way to use the 'hold' command to keep only selected graphs and get rid of the others?

Thanks in advance

I am not certain what you want to do. You may not need to use hold at all.

Try this:

x = linspace(-1, 1);
figure(1)
L1 = line('XData',x, 'YData',2*x);
L2 = line('XData',x, 'YData',x.^2);
set(L1, 'LineStyle','none')                 % Using ‘set’
L1.LineStyle = 'none';                      % Using Structure
grid

set(L1, 'LineStyle','none')

L1.LineStyle = 'none';

I'm not really proficient with MATLAB, could you explain me what these two lines do please?

Thanks

They essentially render ‘L1’ invisible by setting the 'LineStyle' to 'none', or no plotted line.

The information remains in your workspace, however the ‘L1’ line (x,y) values depicting it are not plotted.

Thanks Star Strider! Top man!
