模板介紹
這是製作圓餅圖的模板
使用方法
本模板可以指定最多30個扇區及其圖例。六個扇區的參數示例如下：
{{Pie chart
| radius = 100
| thumb =
| caption =
| other =
| label1 =remember
| value1 =16.6
| color1 =2
| label2 =understand
| value2 =16.6
| color2 =3
| label3 =apply
| value3 =16.6
| color3 =5
| label4 =analyze
| value4 =16.6
| color4 =6
| label5 =evaluate
| value5 =16.6
| color5 =9
| label6 =design
| value6 =16.6
| color6 =10
}}
|radius=參數用於設定圓餅圖的半徑，預設為100|thumb=參數可以使整個模板向左或向右浮動顯示，預設值right。|caption=參數可在圖例上方增加題註。|other=用於替換「其他」圖例的顯示文本。- each "labelN" is a string of text that appears in the legend entry for a slice. Omitting it will cause a legend entry to not be shown for that slice.
- each "valueN" is the percentage that the slice represents. Do not include the percent sign. Also note that it is shown in the legend as written (just after the label), without any rounding or other reformatting.
- each "colorN" is a CSS color code or name. If omitted, it will default to the following hues:
- 1. red
- 2. green
- 3. blue
- 4. yellow
- 5. fuchsia
- 6. aqua
- 7. brown
- 8. orange
- 9. purple
- 10. sienna
- 1.
範例
The following example of Template:Pie_chart generates the pie chart show at right.
{{Pie chart
| caption=[[Religion in the Czech Republic]] as of 2001.
| other = yes
| label1 = [[Atheist]]s and [[Agnosticism|agnostics]]
| value1 = 59 | color1 = silver
| label2 = [[Catholic Church|Catholics]]
| value2 = 26.8 | color2 = #008
| label3 = [[Protestantism|Protestants]]
| value3 = 2.5 | color3 = #08f
}}
注意事项
- The template does not render correctly on mobile devices. See this page on the mobile site and a user's report of this issue.
- Minor issues with printing exist. We also need to implement a good fallback for Books.
- The values need to be percentages.
- Google Chrome and Safari do not appear to anti-alias borders, so the lines are a bit jagged.
- No labels can be put on the slices themselves.
- Inherently, it is not possible to save a copy of the chart using the browser's "Save Image" function.

给模板编辑者的说明
This is an experimental template that draws pie charts using a single image, a lot of (inline) CSS code generated by parser functions, and absolutely no JavaScript. It uses a technique for drawing diagonal lines in CSS exploiting the fact that borders set on elements are miter joined. Thus, it is possible to set one border to an opaque color, with the others fully transparent, to form a diagonal line. The angle of the line can be controlled by adjusting the widths of two adjacent borders (one of them opaque) relative to each other.
Note that in the legacy browser Internet Explorer 6, applying transparent borders the standard way does not work. A workaround is used in the form of the CSS class "transborder", which has been added to MediaWiki:Common.css to make this template usable.
Pie slices are drawn in clockwise order in a counterclockwise direction. These pie slices are positioned:
- Below a 200x200px image having a transparent circle on a light-colored background (same as the background color used for CSS class "thumbinner")
- Inside a container element with
overflow: hidden;set
This allows only the part of each slice that is inside the circle to be visible on the page.
Most of the code in {{Pie chart/slice}} is divided into five sections, the first four corresponding to quadrants of the circle and the last to cleanly cover the case in which one slice occupies 100% of the chart.
