如何使用 XMGRACE 中的公共轴从 y 轴上的多个文件中打印第三列（gfortran，Linux 终端）

Question

I have three files of the format '.dat' (available in the link down below), I need to plot their third columns on Y axis while they all have a common first column ( so a common X axis ), how to plot all of them in the same plot on XMGRACE. I know how to plot the third column from a single '.dat' file by xmgrance -block file.dat -bxy 'x-axis column number: y-axis column number . But is there a similar code for multiple files.

I should get a graph like this

您可以对它们进行预处理以使它们成为两列，或者对每个文件重复-block [...] -bxy [...]指令，如下所示：

xmgrace -block file1.dat -bxy 1:3 -block file2.dat -bxy 1:3 -block file3.dat -bxy 1:3
