How to add more names on a plot axis

As shown in the graph below, I have edited to X-axis to include names. At the moment it only shows 6 names. How do I increase the number of names that may be shown on the X-axis? To be a bit more specific, each bar should show its own name underneath it.

I've made use of the folowing code in order to edit the axis.

 % 
ax = gca;
set(ax, 'XTickLabel', y, 'XMinorTick','on'); %Change the YtickLabels to course code.
ax.XTickLabelRotation = 90;

Look at this example

x=1:20
y=randi(10,1,numel(x))
bar(x,y)
n=numel(y)
names=strsplit(sprintf('name%d ',1:n))
ax = gca;
ax.XTick=x
set(ax, 'XTickLabel', names, 'XMinorTick','on'); 
ax.XTickLabelRotation = 90;
