[Errorbar plot] How to set letters/word on x axis properly?

Hello folks,

I'm using this code to create an error bar plot

errorbar(1:1:34,[cell{2,:}],[cell{3,:}],'o');

which results in

When I try add specific names to the x axis with

set(gca,'XtickLabel', cell(1,:));

This happens:

Where i expect the x axis to fill with all supplied names.

cell(1,:)

has the same format as well as the same size as the other ones. Can someone help me?

You didn’t post ‘all the supplied names’ or other details, so writing specific code for your problem is not possible.

Adapt this idea:

Cell{1} = {'k','d','X','b','f'};

figure(1)
plot(1:5, rand(1,5), 'o')
set(gca, 'XTick',1:5, 'XTickLabel',Cell{1})
set(gca, 'XLim',[0 6])

You're right, sorry.

kdXbf is one variable name. here is a part of the cell I'm using:

My code

 names = names';
 VMT = num2cell(ValFinMean);
 VMHT = num2cell(ValFinMeanHalf);
 cell = [names; VMT; VMHT];
 figure;
 errorbar(1:1:34,[cell{2,:}],[cell{3,:}],'o');
 set(gca,'XtickLabel', cell(1,:));

is working if I plot using bar. But it is not working for errorbar.

Maybe it has something to do with how MATLAB assigns the values in the plot to the axis?

[Star Strider]

Again, without your data, writing specific code is impossible. The errorbar function does not seem to be the problem.

This works for me:

Cell{1} = {'kdXbf','f0_fl','qwerty','uiop','asdf'};

figure(1)
errorbar(1:5, rand(1,5), 0.1*randn(1,5), 'o')
set(gca, 'XTick',1:5, 'XTickLabel',Cell{1}, 'TickLabelInterpreter','none')
set(gca, 'XLim',[0 6])

Note — Setting 'TickLabelInterpreter','none' is necessary so that 'f0_fl' prints as it exists in your cell array. Otherwise the underscore is interpreted as printing the following character as a subscript.

Thanks Star Strider,

I've set my default interpreter to latex.

    'TickLabelInterpreter','none'

did the trick. Also,

    'XTick',1:34

was necessary to show all labels. Is there a way to change the font of the labels to latex back again?

[Star Strider]

As always, my pleasure.

The default interpreter is 'latex' since you set it that way. Setting it using gca (‘get current axes’) affects only that axes object, so there is no need to reset it for others. The 'latex' interpreter remains the default.

It’s good practice to always specify 'XTick' locations first when you’re specifying 'XTickLabel' to be certain the labels are plotted where you want them. (I also did that in my example code.)
