Moin,
ich habe in meinem Conky Ringe, diese funktionieren als Graphen. Jetzt würde ich gern dort einen Farbverlauf einbringen. Also von sagen wir als Beispiel gelb bis rot. Habe aber keine Ahnung wie.
Hier mal das von mir angepasste aber nicht erstellte Script:

Ring Meters by londonali1010 (2009)
This script draws percentage meters as rings. It is fully customisable; all options are described in the script.
IMPORTANT: if you are using the 'cpu' function, it will cause a segmentation fault if it tries to draw a ring straight away. The if statement near the end of the script uses a delay to make sure that this doesn't happen. It calculates the length of the delay by the number of updates since Conky started. Generally, a value of 5s is long enough, so if you update Conky every 1s, use update_num > 5 in that if statement (the default). If you only update Conky every 2s, you should change it to update_num > 3; conversely if you update Conky every 0.5s, you should use update_num > 10. ALSO, if you change your Conky, is it best to use "killall conky; conky" to update it, otherwise the update_num will not be reset and you will get an error.
To call this script in Conky, use the following (assuming that you save this script to ~/scripts/rings.lua):
lua_load ~/scripts/rings-v1.2.1.lua
lua_draw_hook_pre ring_stats
Changelog:
+ v1.2.1 -- Fixed minor bug that caused script to crash if conky_parse() returns a nil value (20.10.2009)
+ v1.2 -- Added option for the ending angle of the rings (07.10.2009)
+ v1.1 -- Added options for the starting angle of the rings, and added the "max" variable, to allow for variables that output a numerical value rather than a percentage (29.09.2009)
+ v1.0 -- Original release (28.09.2009)
KTT73: - Adressierung geändert
- Geometrie geändert
- Positionen geändert
- etc.

! Schick doch mal den install-link. Die Farbe wird über "fg_colour" definiert.
