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 /home/akubuntu/conkyJed/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"

--[[ RINGS with SECTORS widget
 v1.1 by wlourf (07 Jan. 2011)
 this widget draws a ring with differents effects 
 http://u-scripts.blogspot.com/2010/08/rings-sectors-widgets.html
 
To call the script in a conky, use, before TEXT
 lua_load /path/to/the/script/rings.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:
xc,yc  - coordinates of the center of the ring,
     default = middle of the conky window
radius  - external radius of the ring, in pixels,
     default = quarter of the width of the conky window
thickness - thickness of the ring, in pixels, default = 10 pixels
start_angle - starting angle of the ring, in degrees, value can be negative,
     default = 0 degree
end_angle - ending angle of the ring, in degrees,
     value must be greater than start_angle, default = 360 degrees
sectors  - number of sectors in the ring, default = 10
gap_sectors - gap between two sectors, in pixels, default = 1 pixel
cap   - the way to close a sector, available values are
    "p" for parallel , default value 
    "r" for radial (follow the radius)
inverse_arc - if set to true, arc will be anticlockwise, default=false
border_size - size of the border, in pixels, default = 0 pixel i.e. no border
fill_sector - if set to true, each sector will be completely filled,
     default=false, this parameter is inoperate if sectors=1
background - if set to false, background will not be drawn, default=true
foreground - if set to false, foreground will not be drawn, default=true

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_colour1 - colour table for background,
     default = {{0,0x00ffff,0.1},{0.5,0x00FFFF,0.5},{1,0x00FFFF,0.1}}
fg_colour1 - colour table for foreground,
     default = {{0,0x00FF00,0.1},{0.5,0x00FF00,1},{1,0x00FF00,0.1}}
bd_colour1 - colour table for border,
     default = {{0,0xFFFF00,0.5},{0.5,0xFFFF00,1},{1,0xFFFF00,0.5}}     

Seconds tables for radials gradients :
bg_colour2 - second colour table for background, default = no second colour
fg_colour2 - second colour table for foreground, default = no second colour
bd_colour2 - second colour table for border, default = no second colour

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 (08 Aug. 2010) original release
v1.1 (07 Jan. 2011) Add draw_me parameter and correct memory leaks, thanks to "Creamy Goodness"
                    text is parsed inside the function, not in the array of settings

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 /home/akubuntu/conkyJed/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"

put .conkyrc in home folder, make it executable
put bargraph_small.lua anywhere you like, but make sure you got the path right.
make sure you got the right font....please refer to your .conkyrc

I didn't fully make it perfect so please edit it to suit you needs.
Enjoy.
