### **关系图支持3种数据形式：** ### **1. SQL数据** 使用SQL形式，可直接连接数据库，将SQl种的数据筛选并显示在图表上。 点击报表编辑器右侧的操作栏，点击“数据”，选择"数据类型"为“SQL数据集”，按步骤操作即可，下边讲解一下各个参数的意思： ``` 备注： 关系图需要绑定两个数据集； ``` * 绑定数据集：是左侧绑定过的数据集，可选择任意一个SQL类型的数据集，主要显示节点数据； * 分类属性：是X轴绑定数据库的字段； * 值属性：是Y轴绑定数据库的字段； * 系列类型：数据类型字段； * 绑定节点关系数据集：绑定的另一个数据集，主要是显示对应关系； * 来源属性：关系数据集中来源字段； * 目标属性：关系数据集中目标字段，来源和目标字段字段是为了显示关系线；   #### **数据库配置字段如下：**   ### **2. 静态API数据** 报表绑定的数据可以是静态API的形式。 点击报表编辑器右侧的操作栏，点击“数据”，选择"数据类型"为“Api数据集”，“Api类型”选择“静态数据”，点击“数据值”，输入静态类型即可，如： ``` { "data":[ {"name":"测试0","value":28,"type":"北航"}, {"name":"测试1","value":9,"type":"南航"}, {"name":"测试2","value":23,"type":"东航"}, {"name":"测试3","value":8,"type":"西航"}, {"name":"测试4","value":8,"type":"中航"}, {"name":"测试5","value":8,"type":"南航"} ], "links":[ {"source":"测试1","target":"测试0"}, {"source":"测试2","target":"测试0"}, {"source":"测试3","target":"测试1"}, {"source":"测试4","target":"测试1"}, {"source":"测试4","target":"测试2"}, {"source":"测试2","target":"测试3"}, {"source":"测试3","target":"测试2"}, {"source":"测试3","target":"测试1"}, {"source":"测试2","target":"测试1"}, {"source":"测试2","target":"测试4"}, {"source":"测试5","target":"测试0"}, {"source":"测试4","target":"测试0"}, {"source":"测试4","target":"测试1"}, {"source":"测试4","target":"测试2"}, {"source":"测试1","target":"测试0"}, {"source":"测试1","target":"测试4"}, {"source":"测试1","target":"测试3"}, {"source":"测试3","target":"测试0"}, {"source":"测试5","target":"测试1"}, {"source":"测试5","target":"测试4"} ]} ```   ### **3. 动态API数据** 绑定的数据也可以是动态API的形式。 点击报表编辑器右侧的操作栏，点击“数据”，选择"数据类型"为“Api数据集”，“Api类型”选择“动态数据”，选择“绑定数据集”，点击“运行”，就可以将数据渲染过来，代码如： ``` { "data":[ {"name":"测试0","value":28,"type":"北航"}, {"name":"测试1","value":9,"type":"南航"}, {"name":"测试2","value":23,"type":"东航"}, {"name":"测试3","value":8,"type":"西航"}, {"name":"测试4","value":8,"type":"中航"}, {"name":"测试5","value":8,"type":"南航"} ], "links":[ {"source":"测试1","target":"测试0"}, {"source":"测试2","target":"测试0"}, {"source":"测试3","target":"测试1"}, {"source":"测试4","target":"测试1"}, {"source":"测试4","target":"测试2"}, {"source":"测试2","target":"测试3"}, {"source":"测试3","target":"测试2"}, {"source":"测试3","target":"测试1"}, {"source":"测试2","target":"测试1"}, {"source":"测试2","target":"测试4"}, {"source":"测试5","target":"测试0"}, {"source":"测试4","target":"测试0"}, {"source":"测试4","target":"测试1"}, {"source":"测试4","target":"测试2"}, {"source":"测试1","target":"测试0"}, {"source":"测试1","target":"测试4"}, {"source":"测试1","target":"测试3"}, {"source":"测试3","target":"测试0"}, {"source":"测试5","target":"测试1"}, {"source":"测试5","target":"测试4"} ]} ```
