Fixed label and title font size

ROOT
1

Dear Experts and All ROOTers,

I noticed that lines like
gStyle->SetTitleSize(0.04,“xyz”);
gStyle->SetLabelSize(0.03,“xyz”);
take a significant fraction of my macros. This is because whenever
I change the number of pads in my canvas I have to adjust the font
size. This is because the font size by default is proportional to the
pad size. This is somewhat counterproductive - at least for me. What
I want is a fixed font size of, say 3 mm, or, say, 10 pixels, independently
of the size of the pad. Is there an elegant way to achieve this? Or, at
least, to increase the minimum font size limit? Thank you for your help

best regards

Hi Dariusz,

You can set the font size in pixels for general use by precision 3, i.e.gStyle->SetTextFont(63); gStyle->SetTextSize(12); Cheers, Ilka

Dear Ilka,

Many thanks. It works for me but only for the horizontal axis. Any idea
how to get this behavior also for the vertical axis?

best regards

for the axis you should use:

SetLabelFont()
SetLabelSize()

All right, what I did was

gStyle->SetLabelFont(63);

but I should have done

gStyle->SetLabelFont(63,“xyz”);

Now it works. Now I have a problem with the pad margins…
Thanks a lot for your help.
