MATLAB: Set string labels for a plot with multiple lines

Question

Hi,

I create a plot with 3 lines with xTickLabels set as follows:

A=[1 2 3 8]; B=[2 4 5 6];
C=[5 7 11 12];
xaxis = [1:4];
semilogy(xaxis,A,'o-',xaxis,B,'o-',xaxis,C,'o-')
xlabel={'sample1','sample2','sample3','sample4'};
set(gca,'xticklabel',xlabel)

I want to mark the 4 points on the xaxis with the strings sample1,sample2,sample3 and sample4.

The above code is not quite doing that. Any suggestions on how to fix this?

Answer 1

A=[1 2 3 8]; B=[2 4 5 6];
C=[5 7 11 12];
xaxis = [1:4];
semilogy(xaxis,A,'o-',xaxis,B,'o-',xaxis,C,'o-')
xlabel1={'sample1','sample2','sample3','sample4'};
xt=xlim
set(gca,'xtick',linspace(xt(1),xt(2),4))
set(gca,'xticklabel',xlabel1)
