Plot along line y = x

I have a function of 2 variables, x and y, and have been asked to plot it in 2D along the line y = x. I've checked the documentation for the plot command but couldn't find any relevant information.

t = linspace(-3, 17, 500);  %arbitrary bounds and number of points
plot3(t, t, f(t, t));

But won't you need to turn your "camera" or viewpoint so that you're looking at a 45 degree angle so that you're looking normal to the vertical y=x plane and not from some arbitrary point in space?

The problem statement doesn't require it. You can add a view() command if you want. Or you could work with the various Camera* axes properties; see http://www.mathworks.com/help/matlab/ref/axes_props.html#CameraPosition
