Tunning data collection interval

Hello guys

What i came across is that the default data collection interval of 5 mins simply make my graphs not readable when im looking at 1 week duration.

Is there anyway to display fewer data points, either aggregating the duration or simply take that particular point, like 1 point/hr?

Tried to create a new attribute package and set the collection interval, but that seems to prevent the no data collected problem, and the collection interval remains at 5 mins.

Any workaround like collecting a new set of data at a larger interval?

Many thanks
