Correcting an error but problem remains.
There was an error when trying to change Xticks. It should have used
Xticks = [0.0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2] % Brackets were missing
But this will not change the format on the graph. It still is 0 and 1
instead of 0.0 and 1.0 that I would prefer. Apparently, using
Xticks = get (gca, 'Xtick') is not the way to accomplish uniform formatting
on the x-axis (or any axis for that matter).
