Force 0 tick to appear in a scatter plot

I cannot make the 0 tick appear nomatter what I tried. Here is my code.

clc, clear, clf
n = 0:10; f = n.^2;
scatter(n,f, 'k', 'filled')
xlim([-1,11]), ylim([-10,120])
ax = gca;
ax.XAxisLocation = 'origin'; ax.YAxisLocation = 'origin';
ax.XTick = -2:2:10; ax.YTick = -20:20:120;
xlabel('n'), ylabel('f(n)=n^2')
title('Sequence f(n)=n^2')
grid on; grid minor

For the sake of clarity, I wanted the ticks in the origin to appear explicitly as in the following figure (the rest of the plot is irrelevant).

ax.XTick = -2:2:10; ax.YTick = -20:20:120;
xlabel('n'), ylabel('f(n)=n^2')
title('Sequence f(n)=n^2')
grid on; grid minor
ax.XTickLabels = -2:2:10;

Thank you very much. But why do we need to use ax.XTick and ax.XTickLabel ?

[Les Beckham]

You are quite welcome.

ax.XTick sets the values of the axis at which you wish to have tick marks. ax.XTickLabel sets the strings (or char vectors) to be used as labels for those tick marks.

BTW - the title of your questions says "stem plot" but this is a scatter. Maybe you could change the title to avoid confusion for people reading this (or searching) in the future?

Very useful comment. Thanks again. I did the correction!
