% Example of doing multiple plots on one graph using "hold"
% Author: F. P. Schloerb

% create arrays for plots
x = 0:10;
y = x.*x;
z = 5*x;

% plot the "y" array
plot(x,y,'b:s');

% hold graph to add plot of z array
hold on
plot(x,z,'k');

% remove the hold so that next plot command redraws everything
hold off
