MATLAB: Plotting values results in an empty plot

Question

Hello,

So I have a function which returns the x and y coordinates like following:

ans = 
     0         0
    0.0333   -0.0000
    0.2333   -0.0000
    0.6329   -0.0005
    1.2312   -0.0021
    2.0279   -0.0054
    3.0246   -0.0087
    4.2158   -0.0096
    5.5612   -0.0071
    7.0035   -0.0030
    8.4943    0.0001
   10.0031    0.0012
   

So I tried plotting plot(ans(1), ans(2)) but it outputs an empty plot.

My first thought was that because the ans(2) values are close to 0 the plot is empty and therefore I tried to change the ylim but couldn't get it to work.

Any ideas as to what can be done?

Thank You.

Try

plot(ans(:,1),ans(:,2))

You were just plotting the first value against the second, not one column against the other.
