How to connect points horizontally and vertically in non-rect grid?

Hey,

I've been working on a problem and have gotten stuck. I've been trying to make a grid of points of a customized shape. I've got the X and Y points of the grid, but I don't know how to completely connect them in 2 directions.

Here is what I have:

Notice how the lines connect in one direction. I want it such that lines go through the "O's" as well. How do I pull this off?

General code:

-giant X matrix with X coordinate of each point. -giant Y matrix of Y coordinate of each point.

figure plot(X,Y,'-o')

Thanks for any help / advice you can give.

Idea 1. Use SURF

[x,y] = ndgrid(0:0.1:2); %Just making random data
x = sin(x).*y;
y = x+y.^2;

figure, surf(x,y,zeros(size(x)),'facecolor','none','marker','o','edgecolor','k');
view(2);

Idea 2. Use PLOT twice, the second time with the matrices transposed.

[x,y] = ndgrid(0:0.1:2);
x = sin(x).*y;
y = x+y.^2;

figure, plot(x,y,'o-')
hold on;
plot(x',y','o-')

Oh wow. The transpose worked perfectly:

Thanks.
