gnuplot> set term png
Terminal type set to 'png'
gnuplot> set output "output.png"
gnuplot> plot "data.txt" using 1:2 with lines
但是，gnuplot无法正确读取日期。你有什么想法吗？
解决：
set term png xffffff
set output "output.png"
set size 17,17
set title "HTTP payload size and response time"
set style data fsteps
set xlabel "Date"
set timefmt "%s"
set format x "%m/%d/%Y %H:%M:%S"
set xdata time
set ylabel "Payload/Response time"
set grid
set key left
plot 'response' usi 1:2 with linespoints
答案 0 :(得分：15)
set xdata time
set timefmt "%s"
set format x "%m/%d/%Y %H:%M:%S"
plot "file.txt" using 1:2 with linespoints
但它会截断分数并从线上掉落点。
