How to plot using data stored in a .mat file?
I have created a .mat file (variable) and it contains 2 columns, each one has 11 numbers. I want to plot column 1 (X axis)against column 2 (Y axis). The problem is whenever I try to plot, it gives me a figure with 2 curves. Both curves have the same X-Axis (numbers ranging from 1 to 11), and the Y-values for the first curves are numbers in my first column, the Y-values for my second curve are numbers in my second column. This is not what I am looking for, What I want is just one curve with X-values from my first column and Y-values coming from the second column. I have tried to change the values for the X axis and Y axis using the 'edit plot', but it is not working. Any idea?I cannot figure out how to make it work. Any ideas?

Did you try
x = yourArray(:, 1); % Y of your first curve. y = yourArray(:, 2); % Y of your second curve. plot(x,y, 'bo-');
or this
scatter(x, y);
