    lua_draw_hook_post
    cause it's not working.
    I apologise, i was being a little too vague
    you still have to put the function name afterwards

    so
    Code:
    lua_load ~/.conky/Graphs/processorhisto.lua
    lua_draw_hook_pre main_function1
    lua_load ~/.conky/Graphs/bargraph_Processors.lua
    lua_draw_hook_post main_function2
    (or whatever the function is called, prbably not main_function1 and 2)

    with most script theres usually something at the top telling you how to call it

    does that make more sense?

    is this what u ment?

    lua_load ~/.conky/Graphs/processorhisto.lua
    lua_draw_hook_pre main_function
    lua_load ~/.conky/Graphs/bargraph_Processors.lua
    lua_draw_hook_post main_function
    cause that didn't work so I thought u ment to put an underscore between pre and main, but that still didn't make it work

    The 2 is suppose to be a box wrapped around the text it is covering. Also there is suppose to be a thermometor beside the temp, but it was a y and I removed it. Thanks to everyone any help is greatly appreciated. I could not get the screen shot to upload or attach.

    Re: Post your .conkyrc files w/ screenshots

    @Arminius
    well, going back to your post on the last page it looks like one of the scripts has "main_graph" as the name of the function called in the conkyrc

    so one would be

    lua_draw_hook_pre main_graph

    post the 2 lua scripts that you are wanting to use and i'll be able to tell you what exactly you need to put in those lines

    Re: Post your .conkyrc files w/ screenshots

    Just a note. I survived the upgrade to the Narwhal. I saved all of my data, but I forgot to backup my bookmarks. I'm "Up and Running" so to speak, but I'm still waiting on some files to transfer back to their old places before I can do the full restoration.

    And... I have to rebuild my bookmarks... I have a photographic memory so we'll see how much of it is stored there. I really do feel like an idiot right now. I'm still going on hiatus, with one exception. I will get Conky running as soon as possible and give you all a screenshot of Xubuntu Narwhal with Conky running.

    --[[ GRAPH widget v1.1 by wlourf (07.01.2011)
        this widget draws some graphs with some effects 
        http://u-scripts.blogspot.com/2010/10/graph-widget.html
        
    To call the script in a conky, use, before TEXT
        lua_load /path/to/the/script/graph.lua
        lua_draw_hook_pre main_graph
    and add one line (blank or not) after TEXT
    
    
    Parameters are :
    3 parameters are mandatory
    name        - the name of the conky variable to display,
                  for example for {$cpu cpu0}, just write name="cpu"
    arg            - the argument of the above variable,
                  for example for {$cpu cpu1}, just write arg="cpu1"
                    arg can be a numerical value if name=""
    max            - the maximum value the above variable can reach,
                  for example for {$cpu cpu1}, just write max=100 or less or more
        
    Optional parameters:
    x,y         - coordinates of the bottom-left corner of the graph,
                  relative to the top-left corner of the conky window 
                  default =  bottom-left corner of the conky window
    width       - width of the graph, default = 100 pixels
    height      - height of the graph, default = 20 pixels
    nb_values   - number of values to display in the graph, default=width 
                  i.e. 1 pixel for 1 value
    autoscale   - if set to true, calculate the max valeu of the y axis and
                  doesn't use the max parameter above, default=false
    skew_x      - skew graph around x axis, défaut = 0
    skew_y      - skew graph around y axis, défaut = 0
    angle        - angle of rotation of the graph in degress, default = 0
                  i.e. a horizontal graph)
    inverse     - if set to true, graph are draw from right to left, default=false
    background  - if set to false, background is not drawn, default=true
    foreground  - if set to false, foreground is not drawn, default=true
                  foreground = plain graph
    bg_bd_size  - size of the border of the background, default=0=no border
    fg_bd_size  - size of the border of the foreground, default=0=no border
    
    
    Colours tables below are defined into braces :
    {position in the gradient (0 to 1), colour in hexadecimal, alpha (0 to 1)}
    example for a single colour table : 
    {{0,0xFFAA00,1}} position parameter doesn't matter
    example for a two-colours table : 
    {{0,0xFFAA00,1},{1,0x00AA00,1}} or {{0.5,0xFFAA00,1},{1,0x00AA00,1}}
    example for a three-colours table : 
    {{0,0xFFAA00,1},{0.5,0xFF0000,1},{1,0x00AA00,1}}
    
    bg_colour    - colour table for background,
                  default = {{0,0x000000,.5},{1,0xFFFFFF,.5}}
    fg_colour    - colour table for foreground,
                  default = {{0,0x00FFFF,1},{1,0x0000FF,1}}
    bg_bd_colour- colour table for background border,
                  default = {{1,0xFFFFFF,1}}              
    fg_bd_colour- colour table for foreground border,
                  default = {{1,0xFFFF00,1}}              
    
    bg_orientation, bg_bd_orientation, fg_orientation, fg_bd_orientation,
                - "orientation" defines the starting point of the gradient,
                  default="nn"
                  there are 8 available starting points : 
                  "nw","nn","ne","ee","se","ss","sw","ww"
                  (n for north, w for west ...)
                  theses 8 points are the 4 corners + the 4 middles of graph
                  so a gradient "nn" will go from "nn" to "ss"
                  a gradient "nw" will go from "nw" to "se"
    
    draw_me     - if set to false, graph is not drawn (default = true)
                  it can be used with a conky string, if the string returns 1, the graph is drawn :
                  example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
                  
    v1.0 (31/10/2010) original release
    v1.1 (07/01/2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

    BARGRAPH WIDGET
    v2.1 by wlourf (07 Jan. 2011)
    this widget draws a bargraph with different effects 
    http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
    	
    To call the script in a conky, use, before TEXT
    	lua_load /path/to/the/script/bargraph.lua
    	lua_draw_hook_pre main_rings
    and add one line (blank or not) after TEXT
    	
    Parameters are :
    3 parameters are mandatory
    name - the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
    arg  - the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
           arg can be a numerical value if name=""
    max  - the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
    	
    Optional parameters:
    x,y	  - coordinates of the starting point of the bar, default = middle of the conky window
    cap	  - end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
    	    http://www.cairographics.org/samples/set_line_cap/
    angle	  - angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
    	    set to 90 for an horizontal bar
    skew_x	  - skew bar around x axis, default = 0
    skew_y	  - skew bar around y axis, default = 0
    blocks    - number of blocks to display for a bar (values >0) , default= 10
    height	  - height of a block, default=10 pixels
    width	  - width of a block, default=20 pixels
    space	  - space between 2 blocks, default=2 pixels
    angle_bar - this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
    radius	  - for cicular bars, internal radius, default=0
    	    with radius, parameter width has no more effect.
    
    Colours below are defined into braces {colour in hexadecimal, alpha}
    fg_colour    - colour of a block ON, default= {0x00FF00,1}
    bg_colour    - colour of a block OFF, default = {0x00FF00,0.5}
    alarm	     - threshold, values after this threshold will use alarm_colour colour , default=max
    alarm_colour - colour of a block greater than alarm, default=fg_colour
    smooth	     - (true or false), create a gradient from fg_colour to bg_colour, default=false 
    mid_colour   - colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
    	       for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
    	       3 colours to gradient created by fg_colour and alarm_colour, default=no mid_colour
    led_effect   - add LED effects to each block, default=no led_effect
    	       if smooth=true, led_effect is not used
    	       possibles values : "r","a","e" for radial, parallel, perdendicular to the bar (just try!)
    	       led_effect has to be used with theses colours :
    fg_led	     - middle colour of a block ON, default = fg_colour
    bg_led	     - middle colour of a block OFF, default = bg_colour
    alarm_led    - middle colour of a block > ALARM,  default = alarm_colour
    
    reflection parameters, not available for circular bars
    reflection_alpha  - add a reflection effect (values from 0 to 1) default = 0 = no reflection
    		    other values = starting opacity
    reflection_scale  - scale of the reflection (default = 1 = height of text)
    reflection_length - length of reflection, define where the opacity will be set to zero
    		    values from 0 to 1, default =1
    reflection	  - position of reflection, relative to a vertical bar, default="b"
    		    possibles values are : "b","t","l","r" for bottom, top, left, right
    draw_me     	  - if set to false, text is not drawn (default = true or 1)
    		    it can be used with a conky string, if the string returns 1, the text is drawn :
    		    example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
    
    v1.0 (10 Feb. 2010) original release
    v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value	
    v1.2 (28 Feb. 2010) just renamed the widget to bargraph
    v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
    v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
    v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

    I know some of the comments are wrong I've recently swapped the code over from a internet traffic .lua, I'll change all that later.

    Code:
    checkdesktop=tonumber(conky_parse(${if_match ${desktop}==1}1${else}0${endif}))
    if checkdesktop==1 then
    <put the section for this bar in.>
    end
    I'm not good at lua code writing, not sure where to put 42dorian's code. Can someone help me ? Here is the bar graph code I'm using.

    Code:
    --[[ BARGRAPH WIDGET
    	v2.1 by wlourf (07 Jan. 2011)
    	this widget draws a bargraph with different effects 
    	http://u-scripts.blogspot.com/2010/07/bargraph-widget.html
    	
    To call the script in a conky, use, before TEXT
    	lua_load /path/to/the/script/bargraph.lua
    	lua_draw_hook_pre main_rings
    and add one line (blank or not) after TEXT
    
    	
    Parameters are :
    3 parameters are mandatory
    name	- the name of the conky variable to display, for example for {$cpu cpu0}, just write name="cpu"
    arg		- the argument of the above variable, for example for {$cpu cpu0}, just write arg="cpu0"
    		  arg can be a numerical value if name=""
    max		- the maximum value the above variable can reach, for example, for {$cpu cpu0}, just write max=100
    	
    Optional parameters:
    x,y		- coordinates of the starting point of the bar, default = middle of the conky window
    cap		- end of cap line, ossibles values are r,b,s (for round, butt, square), default="b"
    		  http://www.cairographics.org/samples/set_line_cap/
    angle	- angle of rotation of the bar in degress, default = 0 (i.e. a vertical bar)
    		  set to 90 for an horizontal bar
    skew_x	- skew bar around x axis, default = 0
    skew_y	- skew bar around y axis, default = 0
    blocks  - number of blocks to display for a bar (values >0) , default= 10
    height	- height of a block, default=10 pixels
    width	- width of a block, default=20 pixels
    space	- space between 2 blocks, default=2 pixels
    angle_bar	- this angle is used to draw a bar on a circular way (ok, this is no more a bar !) default=0
    radius		- for cicular bars, internal radius, default=0
    			  with radius, parameter width has no more effect.
    
    Colours below are defined into braces {colour in hexadecimal, alpha}
    fg_colour	- colour of a block ON, default= {0x00FF00,1}
    bg_colour	- colour of a block OFF, default = {0x00FF00,0.5}
    alarm		- threshold, values after this threshold will use alarm_colour colour , default=max
    alarm_colour - colour of a block greater than alarm, default=fg_colour
    smooth		- (true or false), create a gradient from fg_colour to bg_colour, default=false 
    mid_colour	- colours to add to gradient, with this syntax {position into the gradient (0 to1), colour hexa, alpha}
    			  for example, this table {{0.25,0xff0000,1},{0.5,0x00ff00,1},{0.75,0x0000ff,1}} will add
    			  3 colurs to gradient created by fg_colour and alarm_colour, default=no mid_colour
    led_effect	- add LED effects to each block, default=no led_effect
    			  if smooth=true, led_effect is not used
    			  possibles values : "r","a","e" for radial, parallelel, perdendicular to the bar (just try!)
    			  led_effect has to be used with theses colours :
    fg_led		- middle colour of a block ON, default = fg_colour
    bg_led		- middle colour of a block OFF, default = bg_colour
    alarm_led	- middle colour of a block > ALARM,  default = alarm_colour
    
    reflection parameters, not avaimable for circular bars
    reflection_alpha    - add a reflection effect (values from 0 to 1) default = 0 = no reflection
                          other values = starting opacity
    reflection_scale    - scale of the reflection (default = 1 = height of text)
    reflection_length   - length of reflection, define where the opacity will be set to zero
    					  calues from 0 to 1, default =1
    reflection			- position of reflection, relative to a vertical bar, default="b"
    					  possibles values are : "b","t","l","r" for bottom, top, left, right
    draw_me     - if set to false, text is not drawn (default = true or 1)
                  it can be used with a conky string, if the string returns 1, the text is drawn :
                  example : "${if_empty ${wireless_essid wlan0}}${else}1$endif",
    
    v1.0 (10 Feb. 2010) original release
    v1.1 (13 Feb. 2010) numeric values can be passed instead conky stats with parameters name="", arg = numeric_value	
    v1.2 (28 Feb. 2010) just renamed the widget to bargraph
    v1.3 (03 Mar. 2010) added parameters radius & angle_bar to draw the bar in a circular way
    v2.0 (12 Jul. 2010) rewrite script + add reflection effects and parameters are now set into tables
    v2.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"

    I know some of the comments are wrong I've recently swapped the code over from a internet traffic .lua, I'll change all that later.
    ok so from the top of the lua scripts, wlourf has kindly given the info you need, how to call the script and which function to call specifically

    so you need

    Code:
    # -- Lua Load -- #
    # SET THE PATH TO THE SCRIPT HERE
    #LEAVE AT LEAST ONE LINE, BLANK OR NOT AFTER TEXT
    lua_load ~/.conky/Graphs/processorhisto.lua
    lua_draw_hook_pre main_graph
    lua_load ~/.conky/Graphs/bargraph_Processors.lua
    lua_draw_hook_post main_rings

    Re: Post your .conkyrc files w/ screenshots

    @ akernan

    do you want the whole script to run on a given desktop and not on others?

    then here is the part to adjust

    Code:
    -----------END OF PARAMETERS--------------
    
    
        
        if conky_window == nil then return end
        
        local cs = cairo_xlib_surface_create(conky_window.display, conky_window.drawable, conky_window.visual, conky_window.width, conky_window.height)
        
        cr = cairo_create(cs)    
        --prevent segmentation error when reading cpu state
    --check for correct desktop
    checkdesktop=tonumber(conky_parse("${if_match ${desktop}==1}1${else}0${endif}"))
    
        if tonumber(conky_parse('${updates}'))>3 and checkdesktop==1 then
            for i in pairs(bars_settings) do
                
                draw_multi_bar_graph(bars_settings[i])
                
            end
        end
        cairo_destroy(cr)
        cairo_surface_destroy(cs)
        cr=nil

    Re: Post your .conkyrc files w/ screenshots

    OK..so...After spending most of the weekend beating my head against the keyboard, and stealing bits-and-pieces from all of your Conkys (looks great BTW!!!) I finally have mine all ready to go...I just have a few questions....

    1) on my weather, i stole the scripts and put my location in (and got the weather channel feeds setup....properly i hope) I have that (A) after everything temperature related. any fixs you guys can think of?

    2) The part up top where it shows my CPU freq as 1.6 GHz is not correct (Should be 2.8) the only code I can find is {freq} or {freq_g} and it pulls the wrong info (i am currently working on over clocking, so i can get a stable setup. the set clock is at 2.26, and the bus is 800, so i have no idea where its getting 1.6 from...)

    3) more of a curiosity, how do you get a semi-transparent backing on this? (VinDSL posted a pic not too far back that was perfect, but he didn't post his scripts so i have no info to go on...)

    note - I have only a rudimentary understanding of coding (hence the thieving!) I understand the changing of values and all that but not too much on santax (self admitted n00b...)
