Re: [ferret_users] different fonts through SET TEXT

["Ansley C. Manke" <ansley.b.manke@xxxxxxxx>]

Hi Marco,

Well, the choice at any particular moment is either Hershey or a 
PyFerret system font, not a mix of those, so the setting is either "SET 
TEXT/FONT=" for system fonts or "CANCEL TEXT" for Hershey. You can turn 
the PyFerret fonts on and off as your script draws the plot,, see below.

I'm afraid that much as we'd like to have everything in classic-Ferret 
scripts work without changes when taking advantage of the expanded 
capabilities of PyFerret, there are a few instances like this that will 
need some script re-writing.  You could change your labels to use the 
subscript and superscript methods for PyFerret fonts, 
https://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/commands-reference/SET#pyferret_subscript. 
Or I suppose if it makes sense, do a CANCEL TEXT before drawing the 
moveable labels, and SET TEXT/FONT= afterwards.

yes? set text/font=serif
yes? set text/font=arial/bold/color=blue vtics
yes? go ptest

PLOT/VS/LINE/I=1:314 i*cos(i/20),i*sin(i/20)

yes? ! add a label with a ferret-style superscript, using Hershey font
yes? cancel text
yes? annotate/norm/xpos=0.5/ypos=0.6/halign=0 "super^2"
