Unfortunately, the answer to both of your questions is "no." Regarding the first question, the product automatically selects "one hour average" or "raw" based upon time range to avoid slowing down the chart page load times because it would have to pull too many data points. I can understand why you might want the more granular data and I think it's a good suggestion.
The good news is that we are actively evaluating making updates to the charting in the Storage Manager. If you'd like to make sure your feedback gets considered in that discussion, please add your feedback to that thread.
Thanks for your input!
When I try to follow the "updates to the charting in the Storage Manager" link, I get this error message;

Sorry, the Thwack idea forums had a bit of a technical hiccup this morning. It should work now.
