Display a 1D (Scalar) Array against a 2D (Matrix) Vector in a 3D graph

I have 2 sets of data: "threshold" and "difference". "threshold" is a 1-Dimensional array containing the threshold values that correspond to the number of columns in "difference". "difference" is a 2-D matrix where each column refers to a difference calculated earlier in the function where the number of columns is the same as the number of rows in "threshold". I need to display threshold against difference in a way that I can compare the two in a graph.

1. Is this possible
2. Is there an alternate way that I can use that breaks down "difference"?

*note that size of "difference" is n-by-numel("threshold"), and the size of "threshold" is approximately 30000, where n is a different entity not mentioned here.

For an idea of what I am talking about, see my "Optimal Threshold" Question.
