Vertical xtick Labels in Matlab graphs

This was taken from the mailing list entry available at: https://mailman.cae.wisc.edu/pipermail/help-octave/2009-July/036066.html
--------------------------------

here is a script that illustrates how to rotate the xtick label and put them vertically.

clear

## init demo plot

clf

plot(1:4);

xtick=[1 2 3 4];

set(gca,'xtick',xtick);

xticklabel=["a";"b";"c";"d"];

set(gca,'xticklabel',xticklabel);



## get position of current xtick labels

h = get(gca,'xlabel');

xlabelstring = get(h,'string');

xlabelposition = get(h,'position');



## construct position of new xtick labels

yposition = xlabelposition(2);

yposition = repmat(yposition,length(xtick),1);



## disable current xtick labels

set(gca,'xtick',[]);



## set up new xtick labels and rotate

hnew = text(xtick, yposition, xticklabel);

set(hnew,'rotation',90,'horizontalalignment','right');
