如何在Grafana中查詢Elasticsearch

Question

我在Elasticsearch中有以下數據。（由於數據有點長，我已將它附加在底部。）我試圖弄清楚如何查詢以便在Grafana中的圖形上顯示某些內容。

我知道我在elasticsearch中的數據不適合圖形，但我沒有任何其他樣本數據，我只是想學習如何處理這個查詢。 我用mysql和grafana做過類似的事情。 （數據不適合圖表，但我設法使其像下面的圖像一樣）

我想用Elasticsearch做上面的事情。 由於他們使用Lucene查詢（與Mysql不同），我閱讀了一些相關的信息。 但我沒有找到放在哪里的線索。 我想在圖表上顯示metascore或者投票（請查看底部的Json ）。

我用過郵差。
這是JSON類型數據。 （我想用'投票'或'metascore'出現在圖表上）

如果這些數據無法在圖表上顯示，那么您能否給我一些關於我可以在下面的查詢和度量字段中添加的內容的提示，以便在我有其他樣本數據時可以使用它。 我需要一個像'metascore'這樣的例子應該進入這個領域，你需要@或_並在這里輸入索引，然后輸入等等）
