====Override====

This is a function of the [[class_samplestream|samplestream]] class.

===Description===

This function overrides the default metadata sent from the ARDI server about the query points.

The most common use for this function is to override the //min// and //max// values for analogue channels to fit the real working range rather than the display range.

===Parameters===

^Parameter^Type^Meaning^
|channel|string|The name of the channel to update|
|options|dict|A dictionary of options to override|

===Returns===

Nothing

===Example===

For example, let's assume we have a property called 'Temperature' on an asset called 'Main Motor'.

This property has a default range of between 0 and 250 degrees. But the motor itself always runs between 20 and 40 degrees.

To boost this significance of this channel when training an AI, we can....

   strm.Override('Main Motor Temperature',{'min': 20,'max': 40})
