Re: [Gnuplot-info] Angstroms symbol in Gnuplot

[sgiani <sam...@gm...>]

Dear Thomas,

thanks a lot for the suggestion, it pointed me towards the good direction, I
am satisfied of the result but there is still something I can't understand.

First of all I would like to point out that in your example,


> set xlabel 'Wavelength (\305)'
> 
the "\305" should be between brackets "{\305}"

The rest of the problem, as much as I could deduce, lies probably in the
type of font one uses: in facts I would like to use LaTeX font cmr10.ttf,
and it seems iso_8859_1 encoding it is not totally supported.

I tried to experiment some of the characters listed on the standard
(http://en.wikipedia.org/wiki/ISO_8859-1) within the
> set term png enhanced font "cmr10"
settings

For some amongs them I get the corresponding glyph (as they are called in
the jergon ;-) ), but for others just an empty square box. I tried also the
usual Symbol.ttf font but same story.

Hereafter i post a possible workaround, mixing the font that I desire for
labels (cmr10.ttf) and another that allows me to display the Angstrom
caracter \305 (luxirr.ttf):

> set term png enhanced font "cmr10"
> set xlabel 'Wavelength ({/luxirr.ttf \305})'

Greetings from Switzerland, the land of the constructive compromises! Sam
