Examples[edit]
Example of 6 amounts
The following 2 examples have numbers in the range of 0-100 units, as percentages. The total is assumed as total=100, to calculate the "other" amount by subtracting all brick values from 100.
{{Brick chart
| caption=Example of 6 amounts
| value1=42 | label1=one
| value2=32 | label2=two
| value3=12 | label3=three
| value4=3 | label4=four
| value5=2 | label5=five
| value6=0.4 | label6=six
}}
Note how the bottom value, value6=0.4, generates a "tiny sliver" of a brick, and the calculated remainder, the "other" value is also a decimal amount as 8.6.
The brick colours use the defaults: red, dark green, blue, yellow, purple, and cyan, as the first 6 hues. The next example, below, shows use of some colour parameters by setting: color1, color2, color3.
Religion in the Czech Republic
{{Brick chart
| caption=Religion in the Czech Republic
| label1 = [[Atheist]]s / [[agnostic]]s
| value1 = 59 | color1 = silver
| label2 = [[Catholic Church|Catholics]]
| value2 = 26.8 | color2 = #008
| label3 = [[Protestantism|Protestants]]
| value3 = 2.5 | color3 = #08f
| legend_margin=0 0 0 6px
}}
The 2nd example, for Religion in the Czech Republic, shows the use of indented parameters for the value/color under each label phrase. The color #008 (for "Catholic") is a hexadecimal code for dark blue, using RGB notation, where the 3rd digit "8" is half of blue intensity levels, 0-F.
It is customary to list the larger percentages first, in a table; however, the numbers can be displayed in any order as needed for the text on a page. A small decimal amount, such as 0.4, will show a tiny sliver among the various brick bars.
The option "legend_margin=0 0 0 6px" resets the alignment of the legend boxes, as only 6 pixels from the left margin (default: 3px 0 0 10px).
Seats in the German federal parliament
Larger amounts: The following example has numbers in the range of 0-300 units, as counts. The total is set to total=614. The options stride=20 and brick_size=2.6 scale the bar line segments to fit within the box, rather than 6x times larger, as 614 compared to 100.
{{Brick chart
|caption = Seats in the German federal parliament
|total = 614
|unit = seats
|stride = 20
|brick_size=2.6
|label1=[[Christian Democratic Union (Germany)
|Christian Democratic Union]]
| color1=black
| value1=180
|label2=[[Christian Social Union of Bavaria]]
| color2=#ccf
| value2=46
|label3=[[Social Democratic Party of Germany]]
| color3=red
| value3=222
|label4=[[Free Democratic Party]]
| color4=yellow
| value4=61
|label5=[[The Left Party.PDS]]
| color5=#800
| value5=54
|label6=[[Alliance '90/The Greens]]
| color6=green
| value6=51
}}
Performance considerations[edit]
The Template:Brick_chart draws the chart by using div-tags ("<div>") to show colored bars for line segments of the calculated length. The template can format a brick chart within 1/6 second, so 3 brick charts could appear within a page and add only 1/2 second to reformat, or edit-preview. The initial creation of the template occurred in August 2009; however, the alignment for display problems with overlapped bars was fixed in September 2012, over 3 years later.
