XTicks change in tiled figure if no breakpoint is set before for loop, even if xticks are used

2 views (last 30 days)
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.
