I want to display property data continuosly changing into mashup timeseries chart. Like, ECG...Can anyone help please...

Hi Thangavel,

If I understood correctly your use case, what I would do it so plot property history using the QueryPropertyHistory service and run it every X seconds to update the chart. In other words:

1 - Add the time series chart to the mashup

2 - Add the QueryPropertyHistory service from the Thing that has this historical data (for that you need a Value Stream assigned to it). Check Mashup loaded checkbox

3 - Bind the AllData from the Service to the Chart

4 - Configure the chart according to your scenario

5 - Add a refresh widget to the mashup

6 - Bind the Refresh Widget to the QueryPropertyHistory service.

Calling the service from time to time is the only way I know how to achieve your scenario.

Cheers
