12 lead ECG graph problem

I am a beginner at Matlab and I have 500 samples to manipulate into an Single beat 12 lead ECG. I have found all the corresponding leads via the formula and have used the subplot function to plot each function on a 4x3 figure. The problem I have is the 12 graphs need to be on the same axis with no spaces between them can anyone shed any light on how I would go about this?

If anything is unclear please let me know and I will upload what I have done so far.

Thanks!

Dear Stephen you can do like this:

plot(x1, y1, x2, y2, x3, y3, x4, y4, x5, y5, x6, y6, x7, y7, x8, y8, x9, y9, x10, y10, x11, y11, x12, y12), legends('y1', 'y2', 'y3', 'y4', 'y5', 'y6', 'y7', 'y8', 'y9', 'y10', 'y11', 'y12')

or you can use

hold on

command to plot many graphs in same figure

Use a single figure. Add different X and Y offsets to each of the different plots. For example, for the bottom left add (0,0); for V2 you might add 2 to X and 1 to Y.

If each plot is to be 4 units wide, then add 6*(column - 1) to X.

If each plot is to be 4 units high, then add 6*(row - 1) to Y, where row starts at 1 at the bottom.
