How can I change the font size of the tick labels without changing the font size of the axis labels?

I would like to change the font size of the tick labels of the x-axis of my graph but I don't want any other font size in the y axis to be changed, i.e. I don't want to change the font size of the x-axis label, the y-axis label or the tick labels in the y-axis.

[Marc Jakobi]

xl = get(gca,'XLabel');
xlFontSize = get(xl,'FontSize');
xAX = get(gca,'XAxis');
set(xAX,'FontSize', Fontsize)
set(xl, 'FontSize', xlFontSize);

Note: You have to change the xlabel FontSize back after changing the XAxis FontSize

I get this:

Error using set

Value must be a handle

[Marc Jakobi]

did you type everything correctly?

xAX and xl should be handles if you run the code

xl = get(gca,'XLabel');
xAX = get(gca,'XAxis');

before using set() on them.

Here's a full example:

axes;
xlabel('test')
Fontsize = 18;
xl = get(gca,'XLabel');
xlFontSize = get(xl,'FontSize');
xAX = get(gca,'XAxis');
set(xAX,'FontSize', Fontsize)
set(xl, 'FontSize', xlFontSize);

Copy/paste this into your workspace. If it runs currectly, you must have mistyped something. If it doesn't, "get(gca,'XAxis')" may not be supported by your Matlab version.
