Extension:Graph/Demo/zh

這個頁面顯示一些藉由扩展:图表所產生的範例. 圖表的基礎技術由Vega grammar（documentation）實現. Vega 團隊正在改善other tools，使圖表能夠更容易使用. this tutorial解釋如何使用互動式圖表、 而Vega examples提供一些建構圖表的想法.



圖表模板
透過一些已製作好的模板（如Graph:Chart、Graph:PieChart），可以快速的輸出圖表. 例如：Graph:Chart支援常見的長條圖、圓餅圖和區塊圖.

地圖
這將嵌入Extension:Graph/Demo/Map. 頁面上的JSON標籤將單獨的URL指定為一個國家/地區. 可以參考Extension:Graph/Demo/RawData:WorldMap-iso2-json所包含JSON格式的地圖數據. 在標籤中，可以使用 來為國家/地區增添顏色.

Vega使用 格式的數據，所以使用下方的Lua函式可以快速的轉換數據.

上方Lua函式輸出為Vega格式：

MapTemplate是Lua數據的擴展，是複雜數據的處理範例. （2010年世界人口資料來自聯合國資料） 為了產生這個圖表，首先需要由Lua模組Graph:Utils的 函式擷取RawData:PopulationByCountryHistoric中CSV格式的數據. 這些數據會被當作一個未命名參數並提供給MapTemplate. 再來使用附加參數指定其縮放比例為80%.



註：注意圖例位於錯誤的位置. 藉由小一點的縮放比例，可以消除這個問題.



傳遞Media Wiki模板參數
就像其他Media Wiki模板，將Wiki頁面當作一個模板也可以傳遞參數.

例如不會對 中的填充顏色進行寫死；它將會將填充顏色設為. 所以當模板範例嵌入時沒有參數，圖表呈現 色；但如果嵌入時帶有顏色參數，則會呈現該色.





使用重複圖表的模板
如果有許多相同形式的圖表，這將十分實用：將圖表詳細的JSON格式和附加的維基語法放在模板中，然後只傳遞其參數. （如圖表名或數值）詳細內容可參照這個範例.



疊加兩種數據

直接嵌入
下面是一個利用包含JSON圖表的標籤的例子.

編輯圖表數據
如果頁面直接嵌入$1標籤，可以在視覺化編輯器中編輯圖表；如果要手工編輯JSON，在複製－貼上至頁面之前，建議使用JSON檢查器或JSON編輯器. If the tag's data is directly embedded in the page such as the example above, then if you use VisualEditor to edit the page you can directly edit graph data.
