|Parameter参数           T|pe类型                     Des|ription描述|
|---------------------------|--------------------------------|-------------|
|图形项目ID gitemids     str|ng/array 字符串型/数组   Return on|y graph items with the given IDs. 只返回指定ID的图形项目。|
|图形ID graphids         s|ring/array 字符串型/数组   Return|nly graph items that belong to the given graphs.只返回属于指定图形的图形项目。|
|监控项ID itemids        st|ing/array 字符串型/数组   Return o|ly graph items with the given item IDs.只返回指定监控项ID的图形项目|
|类型 type               i|teger整数型                Retu|n only graph items with the given type. 只返回指定类型的图形项目。<br><br>Refer to the [graph item object page](object#graph_item) for a list of supported graph item types.关于支持的图形项目类型，参见[图形项目对象](object#graph_item)的列表|
|选择图形 selectGraphs   que|y 请求                   Retur|the graph that the item belongs to as an array in the `graphs` property.返回`graphs`参数正确的图像|
|排序条件 sortfield      str|ng/array 字符串型/数组   Sort the|esult by the given properties. 按指定的参数排序<br><br>Possible values are: `gitemid`.可用值为： `gitemid`|
|countOutput|flag|These parameters being common for all `get` methods are described in detail in the [reference commentary](/manual/api/reference_commentary#common_get_method_parameters) page.这些参数对于所有get方法都是通用的，在附录1：参考中，查看详细描述。|
|editable|boolean|^|
|limit|integer|^|
|output|query|^|
|preservekeys|flag|^|
|sortorder|string/array|^|

### Return values 返回值

`(integer/array)` Returns either: 返回整数或数组：

-   an array of objects返回一个对象数组;
-   the count of retrieved objects, if the `countOutput` parameter has
    been used.如果`countOutput`被使用，返回检索对象的计数。

#### Retrieving graph items from a graph 从图形中检索图形项目

Retrieve all graph items used in a graph with additional information
about the item and the
host.检索被图形使用的所有图形项目包含监控项和主机的额外信息
