I have an x label ( starting from 0 in the axis - 1000, 2000, 3000, 4000, 50000, 6000)
I want to change the axis to the following starting from 0 in the axis - 2000, 4000, 6000, 8000, 10000, 12000
I have used the following implementation but not working
labels = [0 2000 4000 6000 8000 10000 12000];
disp(plot(X));
set(gca, 'XTick', 1:length(labels));
set(gca, 'XTickLabel', labels);
Can someone help me out with this
Thanks in advance

The XTick property requires a vector with numeric data, but the XTickLabel property requires a cell array.
labels = [0 2000 4000 6000 8000 10000 12000];
disp(plot(X));
set(gca, 'XTick', 1:numel(labels));%this puts the labels at x=1,2,3,4,5,6,7
set(gca, 'XTickLabel', cellfun(@num2str,num2cell(labels));

Hi Rik
That is exactly what I mean
where it is 1000 i want it to be 2000
and where it is 2000 I want it to be 4000 etc
Thanks for your help in advance

Then you can use this:
labels_real = [0 1000 2000 3000 4000 5000 6000];
labels_fake = [0 2000 4000 6000 8000 10000 12000];
%or just:
%labels_real=0:1000:6000;
%labels_fake=0:2000:12000;
%or even:
%labels_real=0:1000:6000;
%labels_fake=labels_real/2;
disp(plot(X));
set(gca, 'XTick', labels_real);
%this is now optional:
set(gca, 'XTickLabel', cellfun(@num2str,num2cell(labels_fake),'UniformOutput',0);
Thank you Rik
