I want to draw a mesh surface. But when I use that code to draw it, YZ line is disappeared...

x=[1 2 3];

y=[1 2 3 4];

[X,Y]=meshgrid(x,y);

Z=Y;

plot3(X,Y,Z)

x=[1 2 3];
y=[1 2 3 4];
[X,Y]=meshgrid(x,y);
Z=Y;
surf(X,Y,Z)

Wow, thank you so much!! Can you explain why I can't use 'plot3' instead of 'surf'?
