Thread Subject: Several Plots

Please I need your help,
I would like to have several data signals like about 20 signals to be drawn in one plot and after that I can modify any of them,
thanks

% Plot the 20 signals on the same plot :
figure(1)
hold on,
h1=plot(x,y1);
h2=plot(x,y2);
h3=plot(x,y3);
...
h20=plot(x,y20);

% And then, modify them as you like :
set(h1,'Properties','Values')

% In order to know the name of the 'Properties', use the command:
get(h1)

% For example, in order to modify the line with
set(h1,'Linewidth',3)


I hope it helps...

% Dependent Variable
x = (1:10)';
% Signal Data (Columns)
y = rand(10,20)
% Appropriately Sized Dependent Variable
x = repmat(x,1,size(x,2));
% Plot
h = plot(x,y);

%Change stuff
set(h(3),'LineWidth',3)
set(h(8),'LineStyle',':')

Sorry

% Dependent Variable
x = (1:10)';
% Signal Data (Columns)
y = rand(10,20);
% Plot
h = plot(x,y);

set(h(3),'LineWidth',3)
set(h(8),'LineStyle',':')

Also, try "help subplot"
