Gnuplot 具有不同x轴标签的单个直方图多个y轴,gnuplot,histogram,Gnuplot,Histogram,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 zeoli

我的test.dat文件看起来像

我想用两个y轴（第2列为y，第3列为y2）和第1列x轴绘制一个柱状图，在同一柱状图中，第4列为y，第5列为y2必须与第1列绘制，当然颜色不同。脚本如下所示：gnuplot中的newhistogram脚本已相应修改

现在，plot命令作为

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，对于嵌套四个数据，必须显示锂沸石。但它似乎不起作用。任何建议都会有所帮助

谢谢，

几个小问题：

您需要告诉程序使用直方图打印样式。最好的方法是在plot命令之前添加一行：

set style data histogram
plot \
  newhistogram "Sodium Zeolite", \
  'test.dat' using 2:xtic(1) ls 1 ti col axes x1y1, \
  '' using 3 ls 2 ti col axes x1y2, \
  newhistogram "Lithium Zeolite", \
  '' using 4:xtic(1) ls 3 ti col axes x1y1, \
  '' using 5 ls 4 ti col axes x1y2

设置样式数据直方图

关键字是axis，而不是axis

using关键字必须出现在每个plot子句中

每个绘图不必多次使用xticlabels1命令，尽管这也不会造成任何伤害，但标签将在同一位置打印两次

这将提供一个修改后的plot命令：

set style data histogram
plot \
  newhistogram "Sodium Zeolite", \
  'test.dat' using 2:xtic(1) ls 1 ti col axes x1y1, \
  '' using 3 ls 2 ti col axes x1y2, \
  newhistogram "Lithium Zeolite", \
  '' using 4:xtic(1) ls 3 ti col axes x1y1, \
  '' using 5 ls 4 ti col axes x1y2

输出如图所示几个小问题：
