    Sample text

    Presentation graphs also should make their point clearly. Now that you know the results of your analysis, you should find the clearest and most easily understood way of presenting your findings. A presentation graph should make one point and make it well. Finally, some would argue that a presentation graph should look good. Maybe. If it makes its point well, there is no reason it shouldn’t be visually pleasing, too. But that’s an afterthought. Even a presentation graph is about the content, not the packaging.

    The only commands that do so are plot, splot (which is used for three-dimensional graphs, discussed in appendix C), and replot and refresh (both of which repeat the most recent plot or splot command). 2:  The file format and the output filename must be specified separately, using set terminal and set output, respectively.  The graph must be sent to the newly created file in a separate command, using plot, replot, or an equivalent command.  Afterward, the interactive terminal must be restored explicitly.

    The parameters are available in the loaded file in the variables ARG1 through ARG9. 4 You can use call to write simple scripts for gnuplot. Command files are plain text files, usually containing exactly one command per line. Several commands can be combined on a single line by separating them with a semicolon (;)—this also works at the interactive command line. The hash mark (#) is interpreted as a comment character: the rest of the line following a hash mark is ignored. The hash mark isn’t interpreted as a comment character when it appears inside quoted strings.
