gnuplot显示绘图中的实际数据（时间）

Question

我有一系列要绘制的数据。它每周一次。这是巨大的数据，所以我只是修剪了一些

data:

是否可以在每个图中显示实际时间？ 应该在我的示例数据的第二列下显示时间。

这是我的代码：

APPNAME=$1
START=$2
END=$3
FILE=$4
gnuplot -persist <<-EOFMarker
set grid
set terminal png font 'helvetica,11.5' size 850,550
set output '$APPNAME.$START.$END.png' 
set title '$APPNAME $START.$END'  
set ylabel 'Percentage Usage'
set yrange [0:100]
set xlabel 'Client Time'
set xdata time
set timefmt "%Y-%m-%d"
set xrange ["$START":"$END"]
set format x "%m/%d"
set timefmt "%Y-%m-%d %H:%M"
set datafile separator ","
set x2label "Memory  = 60159 mb, SWAP = 4096 mb, Processor Count = 8"  ##change this if you will use for other application
unset label
set key top center box width 1 height 1 opaque
set style line 1 lt 1 lw 3 pt 3 linecolor rgb "red"
plot '$FILE' u 1:2 w lp t 'Memory', '$FILE' u 1:3 w lp t 'Swap'
EOFMarker

谢谢。

不确定，如果我理解正确的话。如果您有几天的数据，那么额外显示时间可能会变得越来越紧。

但是可以做到的： 将行set format x "%m/%d"换成set format x "%m/%d\n%H:%M"，这也会在第二行显示时间。但我想可能没有足够的空间来显示比00:00和12:00更多的xtics。
