Šablon:Brick chart
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
[uredi izvor]- 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).
Examples
[uredi izvor]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
.
{{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).
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
[uredi izvor]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.
