Hello, I am putting a label on a graph using xlabel, and I want to increase the size of the font (to about 30) and possibly bold it (although, this is less important and I have not yet tried this).
I have tired using:
xlabel(text, 'FontSize', 30)
but this produces no notable change in the font size. Thank you in advance for your help!
Edit:
Using:
h = xlabel(printnombrejpg,'FontSize',60);
get(h)
Returns:
Annotation = [ (1 by 1) hg.Annotation array]
BackgroundColor = none
Color = [0 0 0]
DisplayName =
EdgeColor = none
Editing = off
Extent = [-435.849 -11.5896 837.736 8.69217]
FontAngle = normal
FontName = Helvetica
FontSize = [60]
FontUnits = points
FontWeight = normal
HorizontalAlignment = center
LineStyle = -
LineWidth = [0.5]
Margin = [2]
Position = [-5.76923 -4.46355 1.00011]
Rotation = [0]

This is the code that I am using:
f=gcf;
printnombrejpg=strcat(cellname, '_ch_ ', num2str(neuronchan(cell)));
xlabel(printnombrejpg, 'FontSize', 100)
However, the font size does not change. Nor does it change with the methods suggested below... very weird! Thank you, everyone, for your answers!

do you know how to do this in the GUI?

I suggest you edit your original post (read: don't make a new answer) to include the output from this:
xl = xlabel(printnombrejpg, 'FontSize', 100);
get(xl) % Show what this returns...

Thank you for finding this! (Sorry for the late reply).
I'm not sure if I have a courier, is there a way that I can find out? Hopefully this will fix the problem.

h=xlabel('mylabel') %or h=get(gca,'xlabel')
set(h, 'FontSize', 30)
set(h,'FontWeight','bold') %bold font

Well it works for me!
I would suggest you try:
h = xlabel(text,'FontSize',30);
get(h)
and examine the properties. Specifically FontUnits
