MATLAB: Text instead of values in tick

plottick

How can I have text for example: a,b,c,d instead of 1,2,3,4 in xtick? Matlab always tells me that these values must be numeric…Thanks

set(gca,'xtick',[1 2 3 4],'xticklabel',{'a','b','c','d'})

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

Hi Hans,

now I get it. In this special case you have to deactivate the xticklabels, too. This should works fine:

A(1,1:21)= 100000:100020;
B(1:100,1)= 1:100;
C(1:100,1:21)=33;
figure;
pcolor(A,B,C)
set(gca,'xtick',[])
set(gca,'xticklabel',[])

Best regards,

Friedrich
