冷机总功率这个图上数据是通过调用“查询冷站的属性历史信息”这个接口获取，对应请求体如下：

{
    "end_time": "2025-07-30T15:59:59.000Z",
    "group_duration": "PT5M",
    "limit": 1000,
    "offset": 0,
    "properties_keys": [
        "chiller/sumActivePower",

    ],
    "start_time": "2025-07-29T16:00:00.000Z"
}

响应结果如下，对应指标用红色字体标识出来了：

二次管供回水温度这个图上数据先去冷站管理那找到对应冷站，进入冷站详情页面找到如下图对应的二次冷冻水总管的设备对应的设备ID：

接着拿到这个二次冷冻水总管的设备对应的设备ID去调用“查询设备的属性历史信息聚合结果”接口，对应接口请求体如下：

{
    "end_time": "2025-07-30T15:59:59.000Z",
    "group_duration": "PT5M",
    "property_paths": [
        "InfoService/ChilledWaterSupplyTemp",
        "InfoService/ChilledWaterReturnTemp",
        "InfoService/SupplyAndReturnTempDiff"
    ],
    "start_time": "2025-07-29T16:00:00.000Z"
}

响应结果如下，对应指标用红色字体标识出来了：
