I have this data stored as a variable and wanted to plot it onto a graph produced by a different script. I want these to be plotted as points on the graph as opposed to a line. I was wondering what code would be used to do so. Thank you!

(The left column is the y coordinates and the right column is the x coordinates)

ans =
0000    0.2200
0000    1.0571
0000    1.8943
0000    2.7057
0000    3.5171
0000    4.3286
0000    5.1686
0000    5.8429
0000    6.8657
0000    7.7314
0000    8.5657
