Here’s an error message thrown by a NOAA application:
Error: Not Enough Data Available to be Displayed
There are less than 5 observations available for the selected parameter. Attempting to graph this data may give the impression that no data is available, so building of the graph was aborted.
I understand completely what the error message means, mostly because it sounds like the kind of error message that a programmer (like me) would write to describe what had happened. But it does strike me as rather user-hostile.
