【问题描述】:
我的 test.dat 文件看起来像
# Experiment No. Total U_Na-Z (millimoles/g of zeolite) Total Na_Na-Z in melt (mmoles/g zeolite) Total U_Li-Z (millimoles/g of zeolite) Total Na_Li-Z in melt (mmoles/g zeolite)
Experiment No. Total U loading (mmoles/g zeolite) Total Na in melt (mmoles/g of zeolite) Total U loading (mmoles/g zeolite) Total Na in melt (mmoles/g of zeolite)
1 0.074798319 4.60 0.061795848 1.38
2 0.148512605 3.73 0.122910867 1.72
3 0.223310924 4.02 0.216806723 1.46
4 0.287268908 5.26 0.275399753 1.60
我想针对 Col 1(x 轴)绘制一个带有两个 y 轴(Col 2 作为 y,Col 3 作为 y2)的直方图,并且在同一个直方图中,Col 4(作为 y)和 Col 5(因为 y2) 必须针对 Col 1 绘制,当然要使用不同的颜色。脚本如下(来自 gnuplot 的新直方图脚本相应修改)
set terminal postscript eps enhanced colour font 'Times-Roman,12' size 5in,4in
set output "Histogram1.eps"

现在 plot 命令被指定为
plot \
newhistogram "Sodium Zeolite", \
'test.dat' using 2:xtic(1) ls 1 ti col axis x1y1, '' 3:xticlabels(1) ls 2 ti col axis x1y2, \
newhistogram "Lithium Zeolite", \
'' using 4:xtic(1) ls 3 ti col axis x1y1, '' 5:xticlabels(1) ls 4 ti col axis x1y2
在 x 轴上,对于前四个数据,必须显示“钠沸石”,对于巢四,必须显示“锂沸石”。但这似乎不起作用。任何建议都会有所帮助。
谢谢你,
