I found the dojo for realtime draw https://www.telerik.com/forums/redraw-in-real-time.
What is the best way to implement this for measurement data in 100-ms-steps from a server with database?
At first call, the read method for the DataSourceRequest in the Controller class can send the newest datapoints of the last minute (600 datapoints).
The next calls from the timeout event should only send the newer values.
That is no problem to realize it in the C# controller classs.
In a normal chart the data are overwritten. How can I append this values?
Possible by using of the datasource events push or requestEnd? Is there an example available?
