gnuplot, png and degrees

[Bernd Fuhrmann]

Hello,

I want to use a gnuplot (Linux version 3.7, p0.1) generated png-picture
in a html-file.
There's a special character (°, degrees) in the picture.
It works fine if a type:

path>gnuplot
gnplot> load "weather.gnu"

The contents of the weather.gnu is:
#set terminal png
#set output "temp.png"
set encoding iso_8859_1
set ylabel "Temperature (°C)"
plot "dat" u 1:7 w l

It doesn't work if I remove the comments. The png-output doesn't show
the
special character "°".

Can anybody help me ?

Best regards
Bernd.

There are two reasons for that.

1) terminal png doesn't support 'set encoding' at all. Many terminal drivers
don't.
2) the fonts used by terminal png don't have the \degrees symbol.

In other words: sorry, but you're stuck.
