Hello gautham
That's 480 values per day and roughly 14400 per month - but your Post title mentions cloud stream? So is the data being stored directly on an internet-based Server, from which you can download the data required on demand? If so, we would need to know what database is used to store the data, the format etc.
Not sure, but I think it might be difficult to study a chart with so many values on a phone screen (but perhaps you have an Android Tablet?).
