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]
String = cr45f__ch_24
Units = data
Interpreter = tex
VerticalAlignment = cap
BeingDeleted = off
ButtonDownFcn =
Children = []
Clipping = off
CreateFcn =

BusyAction = queue
HandleVisibility = off
HitTest = on
Interruptible = on
Parent = [222.028]
Selected = off
SelectionHighlight = on

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...

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
