You don't show the code to generate the plot, but
ylim(ax1,[0 50])
ax1.Ytick=[1 10:50])
will work for the y-axes; of course the data itself will have to be in that range or it won't show up--such a mismatch is probably why what you've tried doesn't appear to work as you expect.
For the x-axes, you'll have to plot against two point values or use categorical variables
x=categorical({'Morning','Final'});
x=repmat(x,5,1);
y=(randi(50,5,2));
plot(x,y,'o')
ylim([0 50])
hAx=gca;
hAx.YTick=[1 10:10:50];
yields
for first crude approximation.
