This trick is helpful for changing PDB residue numbers to match the actual protein residue numbers. You can use a mix of both the number and words in the tic marks, too.
The bottom x labels are xtics and the top x labels are x2tics. You can place arrows on your graph at set positions. The default arrow includes one arrowhead. That can be changed to none or both with nohead or heads , respectively. Once labels are unneeded or unwanted, you can use commands like unset key and unset arrow 1 to remove them from the plotting area. There are multiple plot styles afforded by gnuplot. Some examples include plotting with boxes useful for EDA plots; w boxes , points useful for backbone angles; w points , lines useful for distances; w lines and smoothed lines useful for almost everything else; w lines s bezier.
Because of how gnuplot plots information like someone makes a sandwich bread, cover the bread with peanut butter, hide the peanut butter with bananas, hide the bananas with more bread , data sets can be completely obscured from the seen plot.
