select data cannot be charted, please select a new range

I am now trying this for 4 days in a row and it's taking me in cycles. I am unable to chart or metric data as a dashboard widget. I keep on getting the error


select data cannot be charted, please select a new range 


No matter if i use a default sheet, please note i am not trying to trend from a row report or a summary report but from a sheet. This has been working for me in the past.


Can someone let me know what is wrong ?


I am on a 30 day trial - could this be a reason ?
