Re: Angstroms symbol in Gnuplot

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

you don't need a special file.
define GDFONTPATH and then give the filename
(without extension) as font name when setting the
terminal to png.

an example:

i want to use luxi roman regular, the font file is there:

/usr/share/fonts/truetype/luxirr.ttf

in the shell i set:

export GDFONTPATH=/usr/share/fonts/truetype

and in gnuplot:

set encoding iso_8859_1
set xlabel 'Wavelength (\305)'
set term png enhanced font luxirr
set output 'test.png'
plot x
set output
