how to convert date into text fomat

Share icon

Hi All,
I`m processing my data and need to make category plot.
Right now I need to use date"Day column" as x-axis which igor dose not allow me to do that.
I need change the format from "date" to "text"

Is there anyone can teach me how to do that ？

My data was attached if you want to look at it.
Thank you very much.

The "day" wave is numeric and is actually the full date and time as the number of seconds elapsed since Jan 1, 1904.

To get a corresponding text wave with that date (only), you can do this:

Make/O/T/N=(numpnts(day)) dayAsText= Secs2Date(day,0)

Thank you so much Jim. It is very help. Can I choose only to show Month and year, such as 04/2012 instead of 04/01/2012 ?
Thank you very much.

•Make/O/T/N=(numpnts(day)) dayAsText= Secs2Date(day,0)
•dayAsText = StringFromList(0, dayAsText, "/")+"/"+StringFromList(2,dayAsText,"/")
