Why the 'xticklabels' mismatch the 'xticks' when resizing a figure?

I am plotting a figure using the following code.

x=1:1:9;
y=sin(x);
figure
plot(x,y);

Now I would like to change the 'xticks' from [0,5,10] to {'10','15','20'}.

 

set(gca,'xticklabel',{'10';'15';'20'});

Then if I resize the figure the 'xticklabels' does not match the original ticks. 

How do I resolve this issue?

This is expected behavior of MATLAB when no 'xticks' is nominated and the number of assigned 'xticklabels' does not match the number of 'xticks' in a figure. If the number of 'xticklabels' is larger than the 'xticks' number (say n), then the first n 'xticklabels' will show up after rescaling the figure. If the number of 'xticklabels' is smaller than the 'xticks' number (say n), then the n 'xticklabels' will repeatedly show up after rescaling the figure.

The workaround here is to set the 'xticks' before setting the 'xticklabels' using the following code, so that the number of 'xticks' and 'xticklabels' will be the same.

set(gca,'xtick',expectedTicks);
set(gca,'xticklabel',expectedTickLabels);
