问题描述

我有几个名为data_x.dat的文件，其中x的范围从1到10.我正在gnuplot中寻找可以让我直接在同一图中绘制第二列的所有文件，而不是

I have several files called data_x.dat, where x ranges from 1 to 10. I'm looking for something in gnuplot that would allow me to directly plot the second column agains the first one of all of the files in the same graph, instead of doing

p "data_1.dat" u 1:2, "data_2.dat" u 1:2, ..., "data_10.dat" u 1:2

，键入速度慢.像这样:

which is slow to type. Something like:

p "data_*" u 1:2

是我要寻找的. gnuplot是否存在?.

is what I'm looking for. Does it exist for gnuplot?.

谢谢.

推荐答案

使用内联迭代:

plot for [i=1:10] sprintf("data_%d.dat", i) u 1:2
