Dear all! I could not find answer of this question. How to display surface in XY plane with the code? Here is my code:
Z1=reshape(u1,J,I);
[X,Y]=meshgrid(t,x);
surf(X,Y,Z1,Z1);
colorbar;
shading interp;
caxis([0 8]);
axis([-5 5 -5 5 0 10]);
Sorry if question already has been asked. And I apologize for my English:)

By deafult it displays in isometric projection, but I want to display it in XY plane

How can you display a surface (assume 3D) in a plane (like a piece of paper)? Are you looking for contour()?

Thank you a lot! It is what I wanted. It doesn't work, but I'll find how to use it (view([0 89]) works, but view(2), that means view([0 90]), doesn't).

A few years later, but what I did in my code which was similar, after to create the figure, I put the comand:
view ([0 0 90])
so, I get the X-Y view
if I want the X-Z view, I use:
view ([0 -90 0])
I guess it depends of the arrangment of your view.

"I want to display it in XY plane"
You mean as an image or contour map? In which case, use imagesc or contour. doc contour gives other options as well (filled contours, and so on).

Sorry, I am so stupid... When Matlab executed the code, I click on image with right mouse button and choose 'Go to X-Y view'. I want to do the same operation, but without mouse. Just using the code.
