| `hide` | boolean | No | *(Inherited from [DataQuery](#dataquery))*
true if query is disabled (ie should not be returned to the dashboard) |

### DataQuery
These are the common properties available to all queries in all datasources.
Specific implementations will *extend* this interface, adding the required
properties for the given context.
