一. 基础篇: 在linux命令提示符下运行gnuplot命令启动,输入quit或q或exit退出. 1.plot命令 gnuplot> plot sin(x) with line linetype 3 linewidth 2 或 gnuplot> plot sin(x) w l lt 3 lw 2 %用线画,线的类型(包括颜色与虚线的类型)是3,线的宽度是2,对函数sin(x)作图 gnuplot> plot sin(x) with point pointty
发现gnuplot在mac上编译安装相当方便,在线下为了測试java老堆和lucene索引大小,须要绘制两条线,可是直接点连的线很难看,所以后面使用贝塞尔曲线. 脚本例如以下: #! /usr/local/bin/gnuplot -p set terminal canvas; set output "canvas.html" set title "Illustration"; set xlabel "Time(Unit:second)"; set
在coursera看机器学习课程的时候用到Octave来做数据处理,但是装了之后用plot画图时就会报错: set terminal aqua enhanced title "Figure 1" size 560 420 font "*,6" dashlength 1 ^ line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list 在plot之前需要一句setenv(
