GNUPlot TimeFmt Issue

So I'm pretty new to GnuPlot, and 开发者_运维问答I can't seem to find out why I'm getting the error I am.

Here's a sample of my data.txt file in the format (irrelevant id,name,time) :

3|Harpos|2010-08-28 02:44:55
4|Harpos|2010-08-29 02:22:25
5|Harpos|2010-08-29 02:09:19
26|Harpos|2010-09-03 03:01:09

With the following configurations (the xrange is the ultimate bounds of my data):

set xdata time
set timefmt x "%Y-%m-%d %H:%M:%S"
set xrange ["2010-08-28 02:44:55":"2010-12-19 16:46:55"]
set yrange [0:500]

What I'm trying to plot is this:

plot '/Users/kyleturner/Desktop/Harpos-placeholder.txt' using 0:3

As I'm trying to generate the # of occurrences (0 being the sequence # for each occurrence) in my data that happen at a specific time (over series of months).

However, I keep getting the error:

"Bad format character"

Am I executing the "using" command incorrectly? Can someone steer me in the right direction? Once I get this down I'll be able to run some extensive sqlite queries to start generating some visuals.

Thank you for your help, please let me know if I missed any details.

I think you are missing

set datafile separator "|"

Also, it seems you want to have the date on the x-axis, and so you probably want

plot '/Users/kyleturner/Desktop/Harpos-placeholder.txt' using 3:0

Your handling of the time format is fine.
