[Gnuplot-info] Problems plotting from data file...

[Eric H. <eh...@mi...>]

Hello all,

 

I have a data file in the format:

 

18.327  2005-01-29        18:12:15

22.642  2005-01-29        18:12:14

33.551  2005-01-29        18:12:13

20.103  2005-01-29        18:12:12

23.298  2005-01-29        18:12:11

24.456  2005-01-29        18:12:10

21.519  2005-01-29        18:12:09

24.372  2005-01-29        18:12:08

28.488  2005-01-29        18:12:07

42.732  2005-01-29        18:12:06

50.049  2005-01-29        18:12:05

51.193  2005-01-29        18:12:04

53.216  2005-01-29        18:12:03

57.945  2005-01-29        18:12:02

64.788  2005-01-29        18:12:01

63.525  2005-01-29        18:12:00

 

As you can see my data file consist of datetime fields and the current time
is pushed on top of my data file. My question is how do I tell gnuplot to
plot the file as it is? Currently gnuplot plots the file in ascending order
and I need it to be plotted in descending order (which is the format of my
datafile). Also keep in mind that I'm using timefmt for HH:MM:SS as my X
axis and the decimal numbers for the Y axis. And I can't set the X range
like plot ["18:00":"12:00"] because the contents of my data file change.

 

Any help would be greatly appreciated.

 

Thanks,

 

Eric Hudson
