图中有两个“带盒子"的地块. gnuplot彼此相邻 [英] Two plots "with boxes" next to each other with gnuplot

问题描述

我正在尝试在一张图中绘制两个数据系列，作为gnuplot中的框.该脚本当前如下所示:

I am trying to have two data series plotted in one graph as boxes in gnuplot. The script looks like this currently:

set terminal postscript eps enhanced color
set title "Distribution of the extrepreneur PnL. Loan $6."
set output 'pnl_loan6.eps'


#set xrange [0:]
set xlabel "Discounted profit"

set style fill solid 0.8 border -1
plot 'pnl_loan6.txt' using 1:2 title 'PnL high risk (xi=1)' with boxes,\
     'pnl_loan6.txt' using 1:3 title 'PnL high risk (xi=1.5)' with boxes

但这两个系列重叠.除了重叠之外，我希望一个系列在现有框的左半部分绘制其框，而另一组在右半部分绘制，以使它们有效地交替.我该怎么办?

however the two series overlap. Instead of the overlap I would like to have one series draw its box in the left half of the existing box, and the other one in the right half, so that they effectively alternate. How can I do it?

1. 我尝试了直方图，但这看起来不太好. Xtics不是我所追求的，两列之间有空格.
2. 样本数据(每100列中的前20列):

推荐答案

我不太确定您要做什么，但是也许这种小小的黑客方法可以解决问题:

I am not really sure what you are after but maybe this little hackerish approach will do the trick:

set style fill solid 0.8 border -1
set boxwidth 0.5 relative
plot 'pnl_loan6.txt' using ($1+1.27684075):2 title 'PnL high risk (xi=1)' with boxes,\
     'pnl_loan6.txt' using ($1-1.27684075):3 title 'PnL high risk (xi=1.5)' with boxes

与脚本的区别是

1. 设置boxwidth相对为0.5
2. 将图偏移x轴上一半的距离(这仅适用于您，因为您的x轴缩放比例是等距的.

无论如何，这是结果图:

Anyhow this is the resulting plot:

PS: 您可能需要考虑使用set logscale y在y轴上进行对数缩放，从而得出此图:

PS: You might want to think about a logarithmic scaling on the y-axis with set logscale y which would result in this plot:
