Octave is giving me the following error while I'm trying to do 2-D plotting:

I'm not sure what it means.  Where do I put the "N"?

you are sending plot as an argument to figure. you probably want to put them on separate lines

figure

plot(X,Y)

The error is coming from figure, so in general you should look at the help for the figure function. like this

help figure

it explains that calling figure with an argument N is useful when you have multiple figures open and you want to switch back to one created earlier.
