I don’t entirely understand what ‘can't seem to make it work’ means, so this is a guess.
You probably need to use the set function to specifically define the x-tick properties you want:
Example —
StationName = {'ABC','DEF','GHI','JKL','MNO','PQR','STU','VWX','YZ1'};
figure(1)
plot(rand(1, 9), rand(1, 9), 'p')
xl = xlim;
xtix = linspace(xl(1),xl(2),length(StationName));
set(gca, 'XTick',xtix, 'XTickLabel',StationName, 'XTickLabelRotation',90)
Similar options exist for the y-axis ticks. See the documentation on Axes Properties (link) for details and other options.
