雙十一銷量實時統計圖表

前言

echarts 是apache的一個孵化專案，這次我們將它和kintone進行整合，實現了kintone門戶頁面的雙十一的銷量實時統計的Dashboard 。

我們先看下效果圖。

折線圖顯示了雙十一期間的產品銷量走勢，而餅圖則顯示了各渠道的產品銷量的佔比，同時他們都是實時變化的。

接下來我們就來看下它是怎麼實現的。

公用的庫

下面是我們要用到的庫：

echarts

kintone JS SDK

※ 這裡不對這兩個庫做具體介紹，如果還不熟悉它們，請先參閱相關檔案。

應用的自定義開發

我們先來模擬一個kintone的銷量統計的應用。

Stp1: 建立新應用

選擇「通過匯入模板檔案建立」。

Step2: 通過匯入模板檔案建立

選擇模板壓縮檔案後，點選建立應用，便建立完成了。

Step3: 建立JavaScript檔案
