拉力賽標籤雲

我在GitHub上發現了一些代碼（https://github.com/RallyCommunity/TagCloud），用於在拉力賽中顯示TagCloud。從概念上看，它看起來不錯，但我似乎無法完成它的工作，並想知道是否有任何可以快速查看的Rally JavaScript專家。拉力賽標籤雲

由於Google Analytics（分析）的網址不正確（根據文檔），並且API被硬編碼爲折舊版本，所以我更新了這些內容，所以稍微修改了它。

我不是JavaScript專家。當我運行它時，它沒有發現任何標籤對故事。

當我在Chrome調試模式下運行這個功能時，我可以取得該URL並在我的瀏覽器中執行它，但它也不會返回任何標籤。它回來了分析的完整結果響應，但沒有標籤，我知道在選定的項目中有對標籤的故事。

任何人的想法？

的代碼是出於過期關於最近期的LBAPI變化 - 特別是使用_Type的VS _TypeHierarchy當然，網址，因爲您已經發現了。請拿起更改，並給它一個旋轉。

謝謝喬爾，我上傳了這些變化，但我仍然得到「沒有找到標籤」。我知道有標籤，因爲我在當前項目中有1,200個故事，所有這些標籤都標有1個或更多標籤。 – trevleyb 2013-03-20 20:03:34

讓我們確認LBAPI顯示標記的故事。當你在瀏覽器中點擊這個URL時，你會得到什麼？（您必須首先登錄到拉力賽）：'https://rally1.rallydev.com/analytics/v2.0/service/rally/workspace/ /artifact/snapshot/query.js?find={'Tags' ：{'$ exists'：true}，'__ At'：'current'，'_ TypeHierarchy'： - 51038，'_ ProjectHierarchy'：}＆fields = ['Tags']＆pagesize = 20000＆start = 0'替換您的工作區和項目 – 2013-03-21 17:03:41

這樣的作品。我找回了一個標籤列表（其中1138個）。「「結果」：[{ 「標籤」：[11034443843,11013683178,11013754606,11013755361]}，{ 「標籤」：[11013683178,11013755361,11034443843,11013754606]}，{ 「標籤」：[11034443843,11013683178,11013754606， 11013755361]}，{「Tags」：[11013754606,11013755361,11034443843,11013683178]}，' – trevleyb 2013-03-21 18:26:47
