我有这样的文件:
Number Data1 Data2
1 9.10 4.022
2 15.27 3.996
3 21.92 4.004
4 21.19 4.026
5 20.67 4.022
6 20.99 4.000
7 19.80 4.004
8 20.01 3.931
9 20.18 4.004
10 19.78 4.007我想用X轴画数字,在Data1中画leftY,用rightY画Data2,但是我想不出怎么做。
谢谢

只是一个简短的带注释的示例,使用保存在文件so.dat中的数据
# Set ticks for 2nd y axis
set y2tics
# We don't want to see the left ticks on the right axis
set ytics nomirror
# Set ranges so that the data points are not on the axis
set xrange [0:11]
set yrange [8:23]
set y2range[3.95:4.05]
# use first line of the file for labels
set key autotitle columnhead
# display key in least busy area
set key bottom right
# Title and axis labels
set title "Nice Try"
set xlabel "Number"
set ylabel "Data1"
set y2label "Data2"
plot "so.dat" using 1:2 axes x1y1 with points pointsize 2,\
"" u 1:3 axes x1y2 w p ps 2 pointtype 6一个人可以做更多的装饰等等,但我认为这是你想要的本质。所产生的图表:
