why is my gnuplot result (png from csv) not what I expected?
(gnuplot 5.2.5, Centos 7) I've tried about 8 google examples and my result is still not even close.
Here is my data:
Timestamp,1016.qmgr,1893.sshd,1.systemd,2017.sshd
2018-11-21.04:23:03,0.1,1.0,4.0,2.0
2018-11-21.04:23:04,0.2,2.0,5.0,4.0
2018-11-21.04:23:05,0.3,3.0,6.0,8.0
Here are my plot settings:
set datafile separator ","
set title "CPU % Usage per task over time"
set ylabel '% CPU'
set xlabel 'Time'
set grid
set term png
set output '10.png'
set key autotitle columnheader
plot for [i=2:5] 'Results.10/CPU.csv' using 1:i'
Basically, I was expecting something like this:
But I got something like this:
Any ideas what to set in the plot parameters file?
plot graph gnuplot

You need to tell gnuplot that the first column contains time data, and also what the format is:
set xdata time
set timefmt "%Y-%m-%d.%H:%M:%S"
There are other ways to do it, but that is the simplest way to deal with time specified as a string.
[amended answer]
If you just want the content of the first column printed along x as an opaque text string, the command is:
plot for [i=2:5] 'Results.10/CPU.csv' using 0:i:xticlabels(1)
Because these strings are very long, you probably will need to rotate the labels so they do not overlap:
set xtics rotate by -45
why? I mean, it's a series of values. Could be A, B, C...

I may have misunderstood what you want. The example plot you showed has time values along the x axis so I thought that is what you wanted. If you just want the content of column 1 printed as an opaque text blob, the command is different. See amended answer
– Ethan
Nov 21 '18 at 18:07
actually that somehow helped. I am still not sure how, as the series that represents the x values is nicely sorted anyway. I had other problems with that plot properties file but I seem to be on top of it now. Thanks!
