Hello everyone,

I am plotting several figures within a for loop, each with a tile layout of 3x3. The x-axis is plotted over 0 to 100%. As the default font size is too small, I have made it larger.

Unfortunately, this operation changes the x-axis ticks from the desired [0 20 40 60 80 100] to [0 50 100 0 50 100], even if I also adjust the x-ticks, as can be seen below.

This effect does not occur if I set a breakpoint directly before the for loop, e.g. in the line ticks = ...

The function consists of 440 lines in which several calculations are performed before the figure is created.

Processing the script with the breaktpoint is not an option for me.

I have already tried changing the font size in various places. Everything I have tried seems to lead to this problem.

Do you have any idea how to solve this problem? Is it perhaps a question of the settings?

Thank you :)

This is without the breakpoint:

This is when I do place the breakpoint in e.g. the line with ticks = 0:20:100; (This is what I want it to result in):

figure(2)
tiledlayout(3, 3);
percent = 0:100;
ticks = 0:20:100;
for i = 1:9
    nexttile(i)
    a = randi(5, 101, 1);
    plot(percent, a)
    h = get(gca,'XTickLabel');
    set(gca,'XTickLabel',h,'fontsize',15)
    xticks(ticks)
end

I can't explain why your approach didn't work, but this seems to work.

figure

tiledlayout(3, 3);

percent = 0:100;

ticks = 0:20:100;

for i = 1:9

nexttile(i)

a = randi(5, 101, 1);

plot(percent, a)

% h = get(gca,'XTickLabel');

% set(gca,'XTickLabel',h,'fontsize',15)

ax = gca;

ax.XAxis.FontSize = 15;

xticks(ticks)

end

Thank you @Les Beckham and @Voss. I have tested the approach and it works within the function for both the x-axis and the y-axis using the suggested approach.
