+Gauges also accept Dear PyGui's usual `parent` argument for adding a gauge to an
+existing container after that container has already been created:
+
+```python
+dpg.add_window(tag="data_input", label="Data Input")
+dpgg.analog_gauge(tag="rpm", parent="data_input", label="RPM")
+```
+
+The `parent` is applied to the gauge's outer group. The gauge's internal drawlist
+is then parented to that group.

 ## GUI-Thread Contract
 
 Dear PyGui item operations must happen on the GUI thread. Gauge creation and runtime updates such as
