Question

I have a plot:

x = [0 1 2 3];
y = [0 0 1 1];

plot (x, y, 'k');

I want to use labels at X-axis, and it works:

set(gca,'XTick',[0:3]) % This automatically sets 
labels = ['0'; 'T'; 'T'; '1';];
set(gca,'XTickLabel',labels)

However, when I change T to T0. It doesn’t work.

Q1: What are the valid strings of XTickLabel?

Q2: How can I use strings like T0, T1. Or is that possible to use characters with subindex like $A_2$ in latex format.

Answer 1

If you want to set strings of different lengths, you need to use cell arrays, i.e.

labels = {'0','T','T0','somethingCompletelyDifferent'}

will work.

If you want to use Latex to format tick labels, you’ll need to download a function from the Matlab File Exchange.
