title: How do I plot some data (using xmgrace in the terminal) using dots, not lines, without explicitly changing it in the GUI?
body: <p>i'm using xmgrace in the terminal, and want the data to be displayed directly as dots instead of lines. Achieving this in the GUI is simple, but I have to read in multiple files, and do not want to change it every time i start xmgrace. Can I add a command to the files that are read in? Or can I use an option in the terminal when I start xmgrace?</p>
