|graphids|string/array|Return only graph items that belong to the given graphs.|
|itemids|string/array|Return only graph items with the given item IDs.|
|type|integer|Return only graph items with the given type.<br><br>Refer to the [graph item object page](object#graph_item) for a list of supported graph item types.|
|selectGraphs|query|Return the graph that the item belongs to as an array in the `graphs` property.|
|sortfield|string/array|Sort the result by the given properties.<br><br>Possible values are: `gitemid`.|

### Return values

### 返回值

`(integer/array)` Returns either:

-   an array of objects;
-   the count of retrieved objects, if the `countOutput` parameter has
    been used.

`(整数/数组)` 返回:

-   一个数组对象;
-   如果使用了 `countOutput` 参数，返回获取的对象的数量.
