Dear Bert and Jeff, Thank you for looking at this. I am surprised my message was not in plain text. It has been configured to send message to the list in plain text earlier before.
The data again please. 1997-11-23 -2.91709629064653 1997-12-07 -0.960255426066815 1997-12-11 -1.98210752999868 1997-12-20 -1.10800598439855 1998-01-01 -1.00090115428118 1998-01-29 -1.03056081882709 1998-03-27 -0.873243859498216 1998-04-09 -2.06378384750109 1998-04-12 -2.06826431469008 1998-04-19 -2.49834620746286 1998-05-02 -6.4357083781542 1998-05-17 -2.25359807972754 1998-05-21 -2.55799006865995 1999-08-22 -2.25114162617707 1999-08-25 -1.47905397376409 1999-09-05 -0.641589808755325 1999-09-09 -0.648954682695949 1999-09-13 -0.726364489272492 1999-09-16 -1.28445236942011 The first column is date and the second is another data of interest. The date is long but note sequential. Runs randomly from 1953 to 2019. I would like to select any range of date from year A to year B. Thank you again for your help.
