[ferret_users] Time Series Plot with Dates on x-axis

[ag <agdc2005@xxxxxxxxx>]

Dear Ferretters:

I am reading the following tab-delimited ASCII file using the simple ferret command: 
SET DATA/FORM=DELIM/SKIP=1 /VAR="v1,v2,v3,v4" "SampleAscii.csv"

-----------------------------
I would like to make a Time series plot with Time on the x-axis based on values from Column 2 above (which is being read as a character string) and the dependent variable from Column 4 above. I am able to make a simple plot with index(record) number on x-axis but am at a loss to figure out how to convert the Column 2 character string so that Ferret will interpret is as a time stamp.

Any pointers are greatly appreciated.

Thanks in advance
