gnuplot filledcurves

完整的作图过程，数据，最后结果如下所示，其中数据只列出了一部分：

set term pdf
set output "f11_cpu.pdf"
set grid
set title "CPU Total for Insert MongoDB"
set xlabel "Time (second)"
set ylabel "CPU%"

set xrange [0:300]
set yrange [0:100]
set key horizontal

set style data filledcurves
set style fill transparent pattern 1
plot "f11_cpu.txt" using 1:2 with filledcurves xy=0,0 lw 1 title "User%", '' using 1:2: 3 with filledcurves xy=0,0 lw 1 title "Sys%", '' using 1:3:4 with filledcurves lw 1 title "Wait%"

用gnuplot画filledcurves图一直不显示边线，大家可以帮忙看下吗。我的画图命令和数据如下：

set term pdf

set output "test.pdf"

set xlabel "Time (second)"

set ylabel "CPU%"



set xrange [0:300]

set yrange [0:100]



set style data filledcurves

set style fill transparent pattern 1

plot "test.txt" using 1:2 with filledcurves xy=0,0 lw 1 title "User%", "" using 1:2:3 with filledcurves lw 1 title "Sys%"

exit

 

 

我的数据格式如下：

1　　30　　70

2　　20　　80

3　　50　　50
