If I have an array that is size 2x60, how do I plot row 2 vs. row 1?

Would it be plot(data(2,:),data(1,:))?

Would it be

plot(data(2,:),data(1,:))

Yes if you want row 2 as the x (independent) variable and row 1 as the y (dependent) variable. Otherwise, reverse them.

No. You reversed them. For example if you say you want to plot the "signal vs. time" or "y vs. x" or "weight vs. height, the vertical/dependent variable comes first in the verbal description, but second in the call to plot(). The horizontal/independent variable comes second in the verbal description, but first in the call to plot().

So if you want to plot y vs. x, it would be plot(x, y), NOT plot(y, x).

Plotting vec1 vs. vec2 would be plot(vec2, vec1), not plot(vec1, vec2).

So in your example plotting row 2 vs. row 1 would be plot(data(1,:),data(2,:)), not plot(data(2,:),data(1,:)) as you had it. This will plot row 2 as a function of row 1, which is what you asked. Your code would plot row 1 as a function of row 2, which is the opposite of what you asked.
