Access Chunk records in MATLAB

xuewei.zhu

May I ask how to read the the following data in MATLAB?

timeSeriesRequestSetup = timeSeries.SetupDataRequest('ATGOV1YZ=R');

timeSeriesRequestSetup.WithView('DISC_FACTR');

timeSeriesRequestSetup.WithInterval(ThomsonReuters.Desktop.SDK.DataAccess.TimeSeries.CommonInterval.Daily);

timeSeriesRequestSetup.From(System.DateTime(2021,06,30));

timeSeriesRequestSetup.To(System.DateTime(2021,07,30));

timeSeriesRequestSetup.OnDataReceived(@DataReceivedCallback);

timeSeriesRequestSetup.CreateAndSend();

When DataReceivedCallback is trigged, the following line returns an empty structure.

records = chunk.Records.GetEnumerator();

How many OnDataReceived events are raised when you execute your code in Matlab, and what's the value of chunk.IsLast property returned into the event handler? Can you also create an event handler for OnStatusUpdated event of ThomsonReuters.Desktop.SDK.DataAccess.TimeSeries.ITimeSeriesDataRequestSetup interface and see if this event is raised and what info you can get out of it about the status of the request?

I can retrieve the data properly with the following code when using Visual Studio.

 request[0]= timeSeries.SetupDataRequest("ATGOV1YZ=R")
    .WithAllFields()
    .WithView("DISC_FACTR")
    .WithInterval(CommonInterval.Daily)
    .From(new DateTime(2021,6, 30))
    .To(new DateTime(2021,7,30))
    .OnDataReceived(OnTSReceived)
    .OnStatusUpdated(OnTSStatus)
    .CreateAndSend();

The OnTSReceived callback was called twice.

On the first call, the value of chunk.IsLast is false and the returned enumerator contains the data from 6/30/2021 to 7/30/2021.

On the second call, the value of chunk.IsLast is true and the returned enumerator is empty.

Yes. I can retrieve data using visual studio as well. But not able to read it in to MATLAB properly.

The OnDataReceived events are raised twice. The first one is empty but the second one is not!

How should I read out the data returned from records.current?

I tried ToBarCode but all properties has no value stored.
