gnuplot draw two plots on the same graph with single column data

Question

There are two data files, say data1.txt: ``` 31231 32312 32323 32323 ``` data2.txt: ``` 32323 54223 32456 45321 ``` I want to draw the two plots on the same graph, how can I use `gnuplot` to realize that? Thank yu very much.

Accepted Answer

You could get two plots on the same graph in one `plot` command with two `datafile` arguments, separated by a comma. For instance

```
  plot [-1:5] 'data1.txt' with points, 'data2.txt' with points
```

would get you something like this:
