Hi,

I have a created a thing which takes real time value from a OPCUA server. Now I want to map those values in a time series chart. How can I make an infotable of those real time data so that I can use it in the time series chart?

Thanks & Regards,

Dipika Sengupta

Dipika Sengupta​,

Are you logging the real time value in value Stream? If yes, you can use QueryPropertyHistory or QueryNamedPropertyHistory or QueryNumberPropertyHistory to get the infotable values.

I hope it helps.

lets consider you have Data table 'X' thing then You can just make a value stream  'Y'-> map 'Y' to the respective 'X'  data table thing, -> value stream 'Y' consist of subscription-> add new subscription with thing 'X' and with change of the property value in 'X' call service to add data table entry's and get datatable entry's -> map this to your time series chart. you can watch this video to understand value stream https://community.thingworx.com/videos/1467
