===Parameters===

{| class="wikitable"
|-
! parameter name !! what it does
|-
|delimiter || string to delimit multiple values when given. default to colon ( : ). normally you do not want to touch this, it's provided for the off-chance you'll want to use colon as part of one of the parameters.
|-
|width ||number. if provided, must be at least 200. default: 500
|-
|height ||number. if provided, must be at least 200. default: 350
|-
|group n || (where "n" is a number. use "group 1", "group 2" etc. for as many groups as there are in the graph) the values to be charted. see below.
|-
|tooltip n || tooltip to be associated with specific bar. If no tooltip for a specific bar is defined, and this bar has a link, then this link will be used as tooltip. Otherwise, the tooltip will be combined from the group name and the value, optionally with "units prefix" and "units suffix". 
|-
|links n || links to articles to be associated with specific bar 
|-
|stack || whether to stack the different groups on top of each other. do not specify to show bars side by side. Any non-empty value means "yes". To say "no", simply do not supply this parameter at all, or leave the value blank.
|-
|{{nowrap|tooltip value accumulation}} || useful only with stack: when set to true, tooltip will show accumulated value of all blocks up to current one
|-
|colors || the colors used to denote the various groups. should have exactly as many values as # of groups. can be given as standard html-recognized color names, or using #xxx or #xxxxxx notation.
|-
|x legends || The legends for the X values.  Wikicode, such as internal links or templates can be used.
|-
|{{nowrap|hide group legends}} || if set to true, group legends will not be shown below chart. Any non-empty value means "yes". To say "no", simply do not supply this parameter at all, or leave the value blank.
|-
|{{Nowrap|scale per group}} || set to use separate Y- scale for each group. leave empty to use one scale for all groups. incompatible with "stack". Note that even if some of the scales are exactly the same, they will be drawn separately when this setting is on. Any non-empty value means "yes". To say "no", simply do not supply this parameter at all, or leave the value blank.
|-
|{{nowrap|units prefix}} || used in tooltip. e.g., $, so values will show as "$500" instead of "500" in the tooltip
|-
|{{nowrap|units suffix}} || ditto for units suffix. use, e.g. "Kg" so values will show as 88Kg instead of 88 in tooltip. underscore ("_") are replaced by spaces, to allow a space between the value and the suffix.
|-
| {{nowrap|group names}} || names of different groups
|-
| {{nowrap|y tick marks}} || number of tick marks on the y axis.  if the value is negative or omitted, the module will attempt to automatically calculate a sensible number of tick marks.
