Hi @DR_10558933 ,

Can you please explain us more about the data binding that done in your line chart? Service and Chart binding properties snap may help us to understand clearly. 

DWORD from kepware will automatically consider as NUMBER basetype in thingworx so that you can able to view the values in Remote Thing level.

Thanks & Regards,

You have to few more steps to show data in line chart,

• Log the Thing property values
  • Options: ValueStream, Stream, External Table
  • Easiest way to log the property values is Value Stream method
• Use "QueryPropertyHistory()" service to pull all logged values.

To log into Value stream:

1. Create value stream with "ValueStream" as Thing Template.

2. Attach the Value Stream into the Thing where the properties needs to be logged.

3. Make property to be "Log"

4. Now, you can use QueryPropertyHistory()

I have more question. How about "log" system that Thingworx used? How long that system record?
