Graph shows only latest points, no line

Running my MSSQL Query every minute. Only the latest data points are on the graph. Refreshing the browser shows the points moving 1 m to the right, but no lines or previous points. Also the time is off by 4 hours.

select top 10 LastSync as [time], FullName, OutPercentUtil, InPercentUtil from dbo.Interfaces
where fullname like ‘%xyz%’.
