Unable to plot 2 columns of a matrix against each other

Hello, I have a 466x2 matrix and I am trying to plot column 1 on the x-axis and column 2 on y. For that, I am trying the following:

I have the matrix antenna1 as

Column 1 Column 2

0.047393 2530

0.047393 2529

0.097389 2513

0.097389 2491

0.147392 2462

0.147392 2423

0.19739 2387

0.19739 2353

0.247396 2328

0.247396 2310 .... and so on

I am plotting the graph using:

figure
hold on
plot(antenna1(:,1),antenna1(:,2))

I get the following graph for this:

This graph shows both lines plotted on the y-axis. I want column 1 on x and column 2 on y.

How do I achieve this?

Thanks for any help.

Try

n = 1 ;  % play around with n
plot(antenna1(1:end-n,1),antenna1(1:end-n,2))

Thank you. It was due to extra pre-initialised rows and columns that were set to 0.
