The uploaded file contains a single variable with size 1x71x38. If that is correct, just use the squeeze function to remove the singleton dimension.

Z = squeeze(Z);

The new size of Z is 71x38.

From here you can create a line plot for each column

plot(Z)

or a 3D surface

surf(Z)

I'm pretty sure this plot was created using the code

plot(Z(:))

Here, the values of X represent the index of the data point. The command Z(:) turns the entire array into a one-column vector. You can see that syntax described in this doc page. What that means is all the columns were placed head-to-tail. There are 71*38 data points, or 2698.
