- From the help files:
- GNUPLOT is a command-driven interactive function plotting program. It
- is case sensitive (commands and function names written in lowercase
- are not the same as those written in CAPS). All command names may be
- abbreviated, as long as the abbreviation is not ambiguous. Any number
- of commands may appear on a line, separated by semicolons (;).
- .......
- `plot` and `splot` are the primary commands of the program. They plot
- functions and data in many, many ways. `plot` is used to plot 2-d
- functions and data, while `splot` plots 3-d surfaces and data.
-
- Syntax:
-
- plot {ranges} <function> {title} {style}
- {, <function> {title} {style}...}
- .......
- where <function> is either a mathematical expression, the name of a
- data file enclosed in quotes, or a pair (`plot`) or triple (`splot`)
- of mathematical expressions in the case of parametric functions.
- ......
- style
- Plots may be displayed in one of six styles: `lines`, `points`,
- `linespoints`, `impulses`, `dots`, or `errorbars`. The `lines` style
- connects adjacent points with lines. The `points` style displays a
- small symbol at each point. The `linespoints` style does both
- `lines` and `points`. The `impulses` style displays a vertical line
- from the x axis (or from the grid base for `splot`) to each point. The
- `dots` style plots a tiny dot at each point; this is useful for
- scatter plots with many points.
-
- gnuplot is free. Try it.
