Am getting data from kepware to thingworx and storing it in the value stream. Now my requirement is to display this data in a timeseries chart and when new data comes in the new data should get appended to the chart and it should look like a continuous(real time) chart.

When you do F12 in our browser the developer tool comes up if you set that to Network, then you will see everything your webpage (mashup) is doing.

This will let you see the Service calls as they happen and if they are firing once a second and how long the service takes to complete.

If that service (retrieval of data to be rendered) takes over 1 second, you'll never be able to run at a 1 second refresh rate.

On the mashup you can pull the values by using the QueryPropertyHistoryValues (or similar QueryPropertyHistory services) on the Entity (or Entity Template and dynamically binding the Entity itself)

Then drop the All Data that is returned on a Time Series chart.

Configuration of the Chart should be optional.

After that make sure the Service is called on mashup load, but also by a refresh widget so you get the running chart.

Hello. I have got a similar task like @sanil one.

So I did the same like you recommended.

Now I have got a strange issue. I push data into Thingworx every 1 second. Timeseries chart renders only every 6-10 seconds showing collected data for the period, despite I dropped autorefresh widget and set a refresh interval of 1 sec.

Is it any way to force timeseries to render data every second? 

Thank you.

Check with the Developer Tool in runtime.

Are you seeing the call trigger once a second?

If so then probably the system can't keep up with your rate of refresh. i.e. it just takes 5 seconds for the data to be fetched and visualized.
