### **關系圖支持3種數據形式：** ### **1. SQL數據** 使用SQL形式，可直接連接數據庫，將SQl種的數據篩選并顯示在圖表上。 點擊報表編輯器右側的操作欄，點擊“數據”，選擇"數據類型"為“SQL數據集”，按步驟操作即可，下邊講解一下各個參數的意思： ``` 備注： 關系圖需要綁定兩個數據集； ``` * 綁定數據集：是左側綁定過的數據集，可選擇任意一個SQL類型的數據集，主要顯示節點數據； * 分類屬性：是X軸綁定數據庫的字段； * 值屬性：是Y軸綁定數據庫的字段； * 系列類型：數據類型字段； * 綁定節點關系數據集：綁定的另一個數據集，主要是顯示對應關系； * 來源屬性：關系數據集中來源字段； * 目標屬性：關系數據集中目標字段，來源和目標字段字段是為了顯示關系線；   #### **數據庫配置字段如下：**   ### **2. 靜態API數據** 報表綁定的數據可以是靜態API的形式。 點擊報表編輯器右側的操作欄，點擊“數據”，選擇"數據類型"為“Api數據集”，“Api類型”選擇“靜態數據”，點擊“數據值”，輸入靜態類型即可，如： ``` { "data":[ {"name":"測試0","value":28,"type":"北航"}, {"name":"測試1","value":9,"type":"南航"}, {"name":"測試2","value":23,"type":"東航"}, {"name":"測試3","value":8,"type":"西航"}, {"name":"測試4","value":8,"type":"中航"}, {"name":"測試5","value":8,"type":"南航"} ], "links":[ {"source":"測試1","target":"測試0"}, {"source":"測試2","target":"測試0"}, {"source":"測試3","target":"測試1"}, {"source":"測試4","target":"測試1"}, {"source":"測試4","target":"測試2"}, {"source":"測試2","target":"測試3"}, {"source":"測試3","target":"測試2"}, {"source":"測試3","target":"測試1"}, {"source":"測試2","target":"測試1"}, {"source":"測試2","target":"測試4"}, {"source":"測試5","target":"測試0"}, {"source":"測試4","target":"測試0"}, {"source":"測試4","target":"測試1"}, {"source":"測試4","target":"測試2"}, {"source":"測試1","target":"測試0"}, {"source":"測試1","target":"測試4"}, {"source":"測試1","target":"測試3"}, {"source":"測試3","target":"測試0"}, {"source":"測試5","target":"測試1"}, {"source":"測試5","target":"測試4"} ]} ```   ### **3. 動態API數據** 綁定的數據也可以是動態API的形式。 點擊報表編輯器右側的操作欄，點擊“數據”，選擇"數據類型"為“Api數據集”，“Api類型”選擇“動態數據”，選擇“綁定數據集”，點擊“運行”，就可以將數據渲染過來，代碼如： ``` { "data":[ {"name":"測試0","value":28,"type":"北航"}, {"name":"測試1","value":9,"type":"南航"}, {"name":"測試2","value":23,"type":"東航"}, {"name":"測試3","value":8,"type":"西航"}, {"name":"測試4","value":8,"type":"中航"}, {"name":"測試5","value":8,"type":"南航"} ], "links":[ {"source":"測試1","target":"測試0"}, {"source":"測試2","target":"測試0"}, {"source":"測試3","target":"測試1"}, {"source":"測試4","target":"測試1"}, {"source":"測試4","target":"測試2"}, {"source":"測試2","target":"測試3"}, {"source":"測試3","target":"測試2"}, {"source":"測試3","target":"測試1"}, {"source":"測試2","target":"測試1"}, {"source":"測試2","target":"測試4"}, {"source":"測試5","target":"測試0"}, {"source":"測試4","target":"測試0"}, {"source":"測試4","target":"測試1"}, {"source":"測試4","target":"測試2"}, {"source":"測試1","target":"測試0"}, {"source":"測試1","target":"測試4"}, {"source":"測試1","target":"測試3"}, {"source":"測試3","target":"測試0"}, {"source":"測試5","target":"測試1"}, {"source":"測試5","target":"測試4"} ]} ```
