xticklabels showing up incomplete

Hi everybody,

So ... somehow my plot won't show me all of my xticklabels ...

What I did: I plotted 18 bins, and wanted to give each of those a specific name, which I realized with the help of defining my individual xticklabel. But when I've run my code, only the first half of them them will appear ... Even if I increase the size of my figure ... After all the bins show up in the correct amount.

x %vector with my xticklabels
set(gca,'xticklabel',x);

What could be the reason for this? And how can I change it? Might be a reason that the length of one xticklabel is too long? I am so confused ...

Best regards!

Please post a running code, which reproduces the problem. Which "bins" show up a wanted? How did you "plot 18 bins". Which "first half"? A screenshot might help.

You're probably not setting the 'XTick' property.

Here's an example that replicates the problem you're describing.

figure
plot(rand(1,20), rand(1,20))
xlab = {'a' 'b' 'c' 'd' 'e' 'f' 'g' 'h' 'i' 'j' 'k' 'l' 'm' 'n' 'o' 'p' 'q' 'r' 's' 't' 'u' 'v' 'w' 'x' 'y' 'z'};
set(gca, 'XTickLabels', xlab)

In that figure (left) you'll only see letters a:k because the original ticks were 0 : 0.1 : 1.

Now set the ticks correctly by using 'XTick'. Here I use space them equally along the x axis but you'll use the x values where your labels should go.

set(gca, 'XTick', linspace(0,1,length(xlab)), 'XTickLabels', xlab)

Now you see all of the labels (right).

Maybe the number of 'XTick' does not equal the number of 'XTickLabel'? This would be clear, if you post the code.

Label = {'1', '2', '3', '4', '5', '6', '7', '8', '9', '10'};
Axes1H = subplot(1,2,1);
plot(1:10);
set(Axes1H, 'XTick', 1:5, 'XTickLabel', Label);

Axes2H = subplot(1,2,2);
plot(1:10);
set(AxesH, 'XTick', 1:10, 'XTickLabel', Label);

Hi! Sorry I am just answering now ... the problem I had in the first place I was able to solve. (it was really just about the xtick property I forgot to set) But by now I am having another though very similar issue ...

I'd like to: show up all of my xticklabels again, but they just won't ...

My code is the following:

subplot(2,1,2);
scatter(t1.s(:,1), t1.diff(:,1),'.');
new_xtick=[t_b.s(:,1)];
set(gca,'xtick',new_xtick);
set(gca,'xticklabel',num2str(new_xtick));
grid on;

[Adam Danz]

num2str() creates 1 string of all your numbers (eg: '2 4 6 8 10'). You need to split them using

strsplit(num2str());

So your code will be

set(gca, 'XTick', new_xtick, 'XTickLabel', strsplit(num2str(new_xtick)))

Thank you for your answer Adam! When I try so, I am getting an Error message:

"Error using regexp The 'STRING' input must be either a char row vector, a cell array of char row vectors, or a string array.

Error in strsplit (line 125) [c, matches] = regexp(str, aDelim, 'split', 'match');"

Do you have an Idea why?

[Adam Danz]

What are the values of new_xtick?

[jrbbrt]

The values of new_xtick are numbers (mostly/maximum 8 digits) which I am getting out of a table. And when I convert them with the help of num2str I get a 80x8 char array.

[jrbbrt]

The values of the char array look like this:

val= '10004000' '20004000' '30004000' etc.

[Adam Danz]

I see.

new_xtick must be a row vector. If it's a column vector, transpose it.

strsplit(num2str(new_xtick'))

Adam, my hero! Thank you, that actually worked for me :)
