hi Mike , I have read that document also but they not describe how to send the data in time series widgets . Also , I have create entity in domain model called "Value" and define attributes like "Xvalue , Yvalue" . and i add time series widgets in data view with entity of "Value" . in the properties of Time Series widgets i add new series with entity of "Value" . but in data points tab i am not able to select "Xvalue" which i define in my "Value Domain Model" .
