Effect of hold command on plot axes

Pls could somebody run the code below and comment on why the axes of the plot are incomplete. Intuitively, I think it's one of the effects of the hold on/off command. Also, the set(...) command threw up errors and I commented them off.

% Demonstration of hold command
angle = 0:30:360;
y1 = 3*cosd(angle);
y2= 10*sind(angle);
clf
hold on
plot(angle, y1, '-sg','lineWidth', 2)
plot(angle, y2, '-dr','lineWidth', 2)
title('Demo of hold command')
hold off
%set(y1,'color', 'r')
%set(y2,'color', 'g')
legend('3*cos(angle)','10*sin(angle)')
%[x, y] = ginput
set(gca, 'lineWidth', 2)

Yes, setting hold on before plotting tends to foul things up -- why would you do that, anyway?

The problem with the set command is that y1 and y2 aren't handle graphics objects handles -- you should save the line handles from the calls to plot to use to modify.
