    Number of rows in QueryPropertyHistory

    Hello All,

    I have a confusion in, how many number of rows valuestream querypropertyhistory returns?

    I have a device with 3 properties (i,j,k) and I am updating these values every minute in timer event.

    In the mashup, I bound thing's  'querypropertyhistory' to the Grid. And I am refreshing 'querypropertyhistory' every minute.

    Result is, number of rows is totally unpredicted way...

    The distance between two time stamps is 1 minute as my timer event is for every minute.

    But I wonder why for few time stamps two entries and for other time stamps, only one entry is there.  Can anyone has better explanation?

    Thank you.

     

    With B/R,
