Thread: Bar graphs from LAU dont work with my conky - help

i know there lots of conky threads, , have read / searched / googled many possible try , work out ive missed im coming blank.

im running vin conkyrc in xubuntu 11.10 (64) , working except bargraphs. strangely call of draw_bg.lua working fine (as tried # out , conky window changed expect).

here section conkyrc:

#####
## load lua shading (optional)
## set path script here.
#
lua_load ~/conky/draw_bg.lua
lua_draw_hook_pre draw_bg

####
## load lua bargraphs (required)
## set path script here.
#
lua_load ~/conky/bargraph.lua
lua_draw_hook_post main_bars

both draw_bg.lua , bargraph.lua in same folder, call 1 think work other?

below contents of bargraph.lua:

standard can see yet dont of graphs in of sections.

hope can help, have missed something, not sure what?

sorry bump, can give me steer on this? im bit out of ideas myself..
