gnuplot xrange真的不是范围吗? [英] Gnuplot xrange not really a range?

问题描述

我尝试在gnuplot上绘制在x轴上没有实际范围顺序的图.

I try to make a plot on gnuplot which has no real range order on x-axis.

--------------------->
1 4 2 20 17 12 10 8

因此，它不是一个真正的函数，就像您用数学知识来解释它一样，但是它的x轴上有某种索引，没有编号顺序，从1到20，但是20可能是第一个，或者在中间..一切都可能混在一起..希望您理解我的意思，因为我希望gnuplot可以解决这个问题.

It's therefore not a real function as you would interpret it with math knowledge, but it has some sort of index on its x-axis which has no numbering order and runs from 1-20 but 20 could be the first, or in the middle.. everything may be mixed.. hope you understand what I mean cause I am hoping gnuplot can handle that.

也许我可以写我的数据文件，以便点2包含应该在y轴上存在的数据，而只是在x轴上四处移动标签?

maybe i can write my data file so that point 2 contains the data that should be there on the y-axis and just move the labels around on x-axis?

推荐答案

解决方案正在使用xticlabels，并在数据文件中添加了额外的列.即

Solution is using xticlabels and add an extra column in the data file. ie

#xdata ydata label 
0 2 1 
1 3 14
2 10 0 
3 8 20 
etc. 

command: plot "data.dat" using 1:2:xticlabels(3) with lp"
