【问题描述】:
我制作了这个实数均匀随机分布(n=1000)的简单累积和直方图:
http://www.filedropper.com/random1_1:random1.dat
而宏是:
unset key
clear
reset
n=120 #number of intervals
max=4. #max value
min=1. #min value
width=(max-min)/n #interval width
#function used to map a value to the intervals
bin(x,width)=width*floor(x/width)+width/2.0 # cosi viene centrato in mezzo
set xtics min,(max-min)/10,max
set boxwidth width
set style fill solid 0.5 border
set ylabel 'Frequency'
set y2label 'Cumulative frequency'
set y2tics 0,100,1000
set ytics nomirror
set xrange [0.9:4.1]
set yrange [0:25]
set terminal pngcairo size 800,500 enhanced font 'Verdana,14'
set output "testCum.png"
plot 'random1.dat' using (bin($1,width)):(1.0) smooth frequency with boxes title 'histogram',\
'' using (bin($1,width)):(1.0) smooth cumulative axis x1y2 w l lt 2 lw 2 lc rgb 'green' title 'cumul'
现在 output.png 是:
如何告诉 Gnuplot 我不仅要获取累积图,还要获取保存在特定 file.dat 中的数字?
