I'm new to this. Currently, I am trying to plot my memory consumption for my server. I'm using Gnuplot and getting stuck at

warning: Skipping data file with no valid points Can't plot with an empty x range!

set title "Memory Growth" font ",20" textcolor lt 2
set xdata time
set timefmt "%m-%d-%y %H:%M:%S"
set format x "%m-%d-%y\t%H:%M:%S"
set xrange ["12/18/19":"12/24/19"]
set format y '%.0s%cB'
set xlabel "Time"
set xtics rotate by -270 
set xtics out offset 0,-1.0
set ylabel "Memory (GB)"
set datafile separator "\,"
plot    'TRDFDSERVER19_System Monitor Log.csv' using 1:2 title '19\ProcessPrivate,Bytes' with line,\
        'TRDFDSERVER19_System Monitor Log.csv' using 1:3 title '19\ProcessVirtual Bytes' with line,\
        'TRDFDSERVER19_System Monitor Log.csv' using 1:4 title '19\ProcessPrivate Bytes' with line,\
        'TRDFDSERVER19_System Monitor Log.csv' using 1:5 title '19\ProcessVirtual Bytes' with line

You have a wrong time format, according to your data it should be 

set timefmt "%m/%d/%y %H:%M:%S"

if you have the format "%m/%d/%Y %H:%M:%S" then you should set the range accordingly:

Instead of 

set xrange ["12/18/19":"12/24/19"]

you should set

set xrange ["12/18/2019":"12/24/2019"]
