由于写小论文的需要，需要用到gnuplot，本到用什么学什么的观点，仅仅学了简单的折线图和柱状图

标题

set title ""

---

坐标轴

标签 set xlabel "" set ylabel "" set xlabel font "Time-Roman,25"

范围 set xrange [:]

主刻度：单位 set xtics set xtics ,, set xtics ("" , ...)

分刻度：主刻度之间 set mxtics

字体 set ytic font "Time-Roman,25"

---

多组数据

using/u 指定使用那一列数据，使用逗号分隔各组数据 plot "" u : title "", "" u :, ...

---

图例

不显示图例 unset key

图例位置 set key center at , set key left/right set key top/bottom set key outside

字体 set key font "Time-Roman,25"

图例名 set key title ""

---

线风格

plot "" with/w linespoints/lp

linestyle 连线风格（包括linetype，linewidth等） linetype 连线种类 linewidth/lw 连线粗细 linecolor/lc 连线颜色 pointtype/pt 点的种类 pointsize/ps 点的大小

显示网格 set grid

---

填充风格

半透明 set style fill transparent solid

无边线 set style fill transparent solid noborder

为了黑白打印，不同花纹填充 set style fill transparent pattern 1 border

---

柱状图

set style data histogram set style histogram clustered gap

---

我的plot

unset title set xlabel "Workload Data Sets" set xlabel font "Times New Roman,15"

set ylabel "System Response Time" set ylabel font "Times New Roman,15"

set xrange [-0.5:2.5] set xtic font "Times New Roman,15"

set yrange [0:1] set ytics 0,0.2,1 set ytic font "Times New Roman,15"

set key top set key outside set key font "Times New Roman,15"

set style fill transparent pattern 1 border

set style data histogram set style histogram clustered gap 1

plot "2g_avg_response_time.dat" u 2:xticlabels(1) title columnheader, "" u 3:xticlabel(1) title columnheader

set output "abc.jpg"
