MATLAB: Xticklabels showing up incomplete

.binincompletex axisxticklabel

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!

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).

MATLAB: How to assign specific numbers (and letters) to the tick marks of a figure

Okay, somehow managed to solve my problem thanks to both of you. Adam appears to be using an older version of MATLAB, but combined with Orion's solution it gave me the idea that led to me fixing my problem.

It's simply

xlab=zeros(rc,1);
for k=1:rc
   xlab(k)=96+k;
end
set(gca,'XTickLabel',char(xlab))

After the image has already been displayed. rc is the number of rows (or columns, since it's a square board).

p.s. With just this, if the board is too big the tick labels will get all wonky. Something like

if rc>11
   set(gca,'XTick',500*(1:rc))
end

might be required.

MATLAB: How to add tick just for the left axis

Here are two methods to show ticks only on the left axis.

Use yyaxis

This method creates a 2nd y axis on the right that is independently customizable and not used (unless you want to use it).

ax = axes(); 
box(ax, 'on')  % default

% Set axis tick length and direction
ax.XAxis.TickLength = [0 0];
ax.YAxis.TickDirection = 'both';
% Create 2nd y-axis on right and set y axes colors
% to match the x-axis color
yyaxis right
ax2 = gca(); 
ax.YAxis(1).Color = ax.XAxis.Color; 
ax.YAxis(2).Color = ax.XAxis.Color; 
% Remove ticks on right axis
ax.YAxis(2).TickValues = []; 
% Return control back to the left axes
yyaxis left

See image below for results.

Use xline and yline at axis limits

ax = axes(); 
box(ax, 'off')  % default
ax.XAxis.TickLength = [0 0];

If you want the y-ticks to be in both directions,

ax.YAxis.TickDirection = 'both';

If you want the right and upper axes lines but without ticks, you can make is appear as though 'box' is 'on' by setting the axis limits and adding a xline and yline.

% This syntax just sets the axis limits to their current value
xlim(ax, xlim(ax))
ylim(ax, ylim(ax))
% Set right and upper axis lines to same color as axes
xline(max(xlim(ax)), 'k-', 'Color', ax.XAxis.Color)
yline(max(ylim(ax)), 'k-', 'Color', ax.YAxis.Color)

If the axis limits change after this change, the pseudo-box lines will no longer be positioned correctly so this should happen after all other plotting and positioning is done on the axes. The first method is therefore safer.

Final result for both methods
