How do I set the datapoint for missing or out or range data?
As an example:
Date Temperature X1 = 04/01/1953 Y1 = 36.7 X2 = 04/02/1953 Y2 = 67.5 X3 = 04/03/1953 Y3 = 9999.9 X4 = 04/04/1953 Y4 = 78.2
Obviously, 9999.9 is not a valid temperature so I need to skip this record and continue. Can a point be set to null so it does not plot?
Thanks in advance.
