customised x data in matlab plot
显示 更早的评论
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));

Sorry for the typo (missing the UniformOutput).
If you only set the XTick property, you don't actually need to set the label. It looked like you wanted to have the label '2000' show up at x=2, so my code does that for you.
So maybe this code is what you meant?
labels = [0 2000 4000 6000 8000 10000 12000];
disp(plot(X));
set(gca, 'XTick', labels);
%this is now optional:
set(gca, 'XTickLabel', cellfun(@num2str,num2cell(labels),'UniformOutput',0);

So where the actual x-postition is 1000 you want to have the label say 2000 etc?

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);
