I found the technical support item that describes how to combine date and time into one column, and I am using this worksheet script: getn (Column number for date: ) date (Column number for time: ) time (Get column numbers); wcol(date)+=wcol(time);
My date is in the yyMMdd format. My time is in the HH:mm:ss.### format. When I have changed the data types for these columns and run the above worksheet script, I get 00:00 for the time for every entry in my date column. If I change subformat from 10 to 14 (for yyMMdd HH:mm:ss which is the closest selection to what I really want: yyMMdd HH:mm:ss.###) I still get the time part of the date column containing 00:00:00 for all entries in the column. Nothing plots correctly.
