This is controlled by the RECOMPUTE_DIMENSIONS property of the axis-text
IDLgrText objects. Default is 0; you should use 1 or 2.

It's easy to specify RECOMPUTE_DIMENSIONS for a text object you create
yourself. But the tick-label objects are generated automatically, so you
have to hunt them down. My MGHgrAxis object does this. The axis object keeps
properties FONT and RECOMPUTE_DIMENSIONS, which it applies to all the text
objects it manages. The code looks like this:

self->GetProperty, TICKTEXT=oticktext, TITLE=otitle
if obj_valid(otitle) then begin
otitle->SetProperty, RECOMPUTE_DIMENSIONS=self.recompute_dimensions
otitle->GetProperty, FONT=font
if not obj_valid(font) then otitle->SetProperty, FONT=self.font
endif
for i=0,n_elements(oticktext)-1 do begin
if obj_valid(oticktext[i]) then begin
oticktext[i]->SetProperty, $
RECOMPUTE_DIMENSIONS=self.recompute_dimensions
oticktext[i]->GetProperty, FONT=font
if not obj_valid(font) then $
oticktext[i]->SetProperty, FONT=self.font
endif
endfor

To look at this code in context, see
