gnuplot中的标准化直方图,带有附加函数图
我有以下脚本来绘制直方图:gnuplot中的标准化直方图,带有附加函数图,gnuplot,histogram,Gnuplot,Histogram,我有以下脚本来绘制直方图: set terminal postscript eps enhanced color set title "Histogram\_CreatesFile" colour1="#00A0ff" colour2="navy" colour3="#ffA000" colour4="#800000" set output 'Histogram_CreatesFile.eps' set yrange [0:] set style fill solid 0.8 border -
set terminal postscript eps enhanced color
set title "Histogram\_CreatesFile"
colour1="#00A0ff"
colour2="navy"
colour3="#ffA000"
colour4="#800000"
set output 'Histogram_CreatesFile.eps'
set yrange [0:]
set style fill solid 0.8 border -1
bin_width = 0.2
set boxwidth bin_width
bin_number(x) = floor(x/bin_width)
rounded(x) = bin_width * ( bin_number(x) + 0.5 )
plot 'Histogram_CreatesFile.txt' using (rounded($1)):(1) smooth frequency with boxes lc rgb colour1 notitle
这应该是一些分布的经验实现,因此,为了更清楚地说明这一点,我想:
我怎样才能做到这一点?我设法解决了这个问题。 (1) 标准化进入冒号后的列,因此plot命令变为:
plot 'ConfUoMBM1validation0_0.txt' using (rounded($1)):(1/(bin_width*STATS_records)) smooth frequency with boxes lc rgb colour1 notitle
(2) 绘制函数非常简单,只需在昏迷后像通常一样进行即可
因此,最终结果是:
set terminal postscript eps enhanced color
set title "ConfUoMBM1validation0 0"
colour1="#00A0ff"
colour2="navy"
colour3="#ffA000"
colour4="#800000"
set output 'ConfUoMBM1validation0_0.eps'
set style fill solid 0.8 border -1
bin_width = 0.926911
set boxwidth bin_width
bin_number(x) = floor(x/bin_width)
rounded(x) = bin_width * ( bin_number(x) + 0.5 )
invsqrt2pi = 0.398942280401433
normal(x,mu,sigma)=sigma<=0?1/0:invsqrt2pi/sigma*exp(-0.5*((x-mu)/sigma)**2)
stats 'ConfUoMBM1validation0_0.txt' using (rounded($1)) nooutput
set xrange [STATS_min-bin_width/2.:STATS_max+bin_width/2.]
set yrange [0:]
plot 'ConfUoMBM1validation0_0.txt' using (rounded($1)):(1/(bin_width*STATS_records)) smooth frequency with boxes lc rgb colour1 notitle, normal(x,-0.14166974006432781,4.6345562297659741) with lines lc rgb colour2 lw 5 notitle
设置终端postscript eps增强颜色
设置标题“ConfUoMBM1validation0”
color1=“#00A0ff”
color2=“海军”
color3=“#ffA000”
color4=“#800000”
设置输出“ConfUoMBM1validation0\u 0.eps”
设置样式填充实体0.8边框-1
箱柜宽度=0.926911
设置箱宽箱宽
箱柜编号(x)=楼层(x/箱柜宽度)
四舍五入(x)=料仓宽度*(料仓编号(x)+0.5)
invsqrt2pi=0.398942280401433
标准(x,mu,sigma)=sigma
