How to repeat a pattern on xticks?

Hi all,

I have the following for a plot. How can I make the A,B,C,D,E repeat for 100 times on the x label with the same patttern A,B,...

set(gca,'XTickLabel',{'A','B','C','D','E'})

Also, is there anyway to make it appear 90° rotated on the x axis?

Try this:

x = 0:24;
y = rand(size(x));

figure
plot(x, y)
set(gca, 'XTick',x, 'XTickLabel',{'A','B','C','D','E'}, 'XTickLabelRotation',90)

I restricted the x-axis to go from 0 to 24 to make it readable. To use 100 values for ‘x’ may require a smaller font as well, although this could affect the font size for both axes. Another option is to increase the figure width using the 'Position' property. See the documentation section on Position and Size for information on that.

@Star Strider @Mathieu NOE Thank you guys both. So another quick question, when my plot is created it's messed up until I make it full size. so is there a way to automatically save as the screen size? maybe using size? thx (I did not name my plot because it's multiple for loops with if statements so I cannot say like PlotX then size of PlotX, it's just a flow of plots :D using the command directly without assigning it to anything)

It depends on the result you want. To change the entire figure size, use the OuterPosition property.

Example —

x = 0:99;
y = rand(size(x));

figure
plot(x, y)
set(gca, 'XTick',x, 'XTickLabel',{'A','B','C','D','E'}, 'XTickLabelRotation',90)
opos = get(gcf,'OuterPosition');
set(gcf, 'OuterPosition',opos+[-750 -500 1050 500])

Experiment with the vector in the last line to get different results. Use the Position property (that apparently does not have a direct link) to change the size of the drawable area.

hello

this is an example for 20 repetition of the 5 letters pattern + 90° rotated

plot(1:100,randn(1,100));
set(gca,'XTick',(1:100),'XTickLabel',repmat({'A','B','C','D','E'},1, 20))
xtickangle(90)

this one works perfectly as well but I could just pick one so I picked the one who commented first. Thank you Mathieu!

that's life ! it's hard to beat a MVP !! I have to admit I still have to learn a few things before I'm up to the task
