Drawing Bar charts: "bar chart"

Parameters

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.
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.
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.
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.
units prefix used in tooltip. e.g., $, so values will show as "$500" instead of "500" in the tooltip
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.
group names names of different groups

Examples

Basic

{{ #invoke:Chart | bar chart
| group 1 = 40 : 50 : 60 : 20
| group 2 = 20 : 60 : 12 : 44
| group 3 = 55 : 14 : 33 : 5
| links 1 = Apple : McCintosh : Golden delicious
| links 2 = Banana : Apricot : Peach
| links 3 = Orange : Pear : Bear
| tooltip 2 = tooltip 1 : tooltip 2 : tooltip 3 : tooltip 4
| colors = green : yellow : orange
| group names = Apple : Banana : Orange
| x legends = Before : During : After : Post mortem
}}

Stacked

Here is the same graph, with more modest height and width, using "stack", and adding "units suffix" for good measure:

{{ #invoke:Chart | bar chart
| height = 250
| width = 300
| stack = 1
| group 1 = 40 : 50 : 60 : 20
| group 2 = 20 : 60 : 12 : 44
| group 3 = 55 : 14 : 33 : 5
| colors = green : yellow : orange
| group names = Apple : Banana : Orange
| units suffix = Kg
| x legends = Before : During : After : Post mortem
}}

Scale per group

It is possible to show each of the groups using different scale and units:

{{ #invoke:Chart | bar chart
| width = 800
| group 1 = 1500000 : 2500000 : 3500000
| group 2 = 200 : 5000 : 45000
| group 3 = 2000 : 5000 : 20000
| colors = red : blue : green
| group names = People : Cars : Average car cost
| x legends = 1920 : 1965 : 2002
| tooltip 2 = : There is no good data for number of cars in 1965. we use 5,000 as best estimate
| units prefix = : : $
| scale per group = 1
}}

Notice the "units prefix" field: we do not need prefix for the first 2 groups, so we use colons with no content. we could write "::$" instead of " : : $".

Also note the special tooltip for the "Cars" number for 1965.


1,000,000
2,000,000
3,000,000

5,000
10,000
15,000
20,000
25,000
30,000
1920
1965
2002
  •   People
  •   Cars
  •   Average car cost
{{ #invoke:Chart | bar chart
| width = 800
| group 1 = 1500000 : 2500000 : 3500000
| group 2 = 200 : 5000 : 45000
| group 3 = 2000 : 5000 : 20000
| colors = red : blue : green
| group names = People : Cars : Average car cost
| x legends = 1920 : 1965 : 2002
| tooltip 2 = : There is no good data for number of cars in 1965. we use 5,000 as best estimate
| units prefix = : : $
| scale per group = 1
}}

Notice the "units prefix" field: we do not need prefix for the first 2 groups, so we use colons with no content. we could write "::$" instead of " : : $".

Also note the special tooltip for the "Cars" number for 1965.


Here is an example with large number of groups - mainly to test how does it look with large number of legends.

If there are many values, x legends can be diluted by using delimiters with nothing in between:


{{ #invoke:Chart | bar chart
| group 1 = 1:2:3:4:5:6:7:8:9:10:11:12:13:14:15:16:17:18:19:20:21:22:23:24:25:26:27:28:29:30

| units suffix = _Things
| group names = Some
| x legends = ::::1940::::::::::1950::::::::::1960::::::::::1970::::::::::1980::::::::::1990::::
