Шаблон:Brick chart/док

Draws a "brick chart" (poor man's substitute for pie charts) as a rectangular-box chart with brick segments inside, useful for showing percentages, seats in a legislature, etc.

Parameters

• value1-value9 – values for each brick. Values can be integers, decimals ("2.4"), formulas, or use '+' in mixed number fractions ("3+1/2").
• label1-label9 – labels for each brick, displayed in the legend
• color1-color9 – web colors to be used for each brick, defaults to various colours
• caption – the caption for the legend
• total   – the total number of bricks (defaults to 100)
• stride – the number of bricks in each row, defaults to 10
• unit   – unit to display in the legend, default to %
• width – the width of the chart in pixels, the height is calculated automatically
• align  – (left|right) where to align the chart, defaults to "right".
• legend_margin=0 0 0 6px – shifts legend boxes 6 pixels from left margin (default: 3px 0 0 10px).

Example of 6 amounts

  one - 42 %

  two - 32 %

  three - 12 %

  four - 3 %

  five - 2 %

  six - 0.4 %

  other - 8.6 %

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

  Atheists / agnostics - 59 %

  Catholics - 26.8 %

  Protestants - 2.5 %

  other - 11.7 %

{{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

  Christian Democratic Union - 180 seats

  Christian Social Union of Bavaria - 46 seats

  Social Democratic Party of Germany - 222 seats

  Free Democratic Party - 61 seats

  The Left Party.PDS - 54 seats

  Alliance '90/The Greens - 51 seats

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

  | color5=#800
  | value5=54

  | color6=green
  | value6=51
}}

Performance considerations

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.
