GNU Info (gnuplot.info)styleDefault styles are chosen with the `set function style` (Note: function style ) and `set data style` (Note: data style ) commands. See `plot with` (Note: with ) for information about how to override the default plotting style for individual functions and data sets. Syntax: set function style <style> set data style <style> show function style show data style The types used for all line and point styles (i.e., solid, dash-dot, color, etc. for lines; circles, squares, crosses, etc. for points) will be either those specified on the `plot` (Note: plot ) or `splot` (Note: splot ) command or will be chosen sequentially from the types available to the terminal in use. Use the command `test` (Note: test ) to see what is available. None of the styles requiring more than two columns of information (e.g., `errorbars` (Note: errorbars )) can be used with splots or function plots. Neither ther `boxes` (Note: boxes ) nor any of the `steps` (Note: steps ) styles can be used with splots. If an inappropriate style is specified, it will be changed to `points` (Note: points ). For 2-d data with more than two columns, `gnuplot` (Note: gnuplot ) is picky about the allowed `errorbar` styles. The `using` (Note: using ) option on the plot command can be used to set up the correct columns for the style you want. (In this discussion, "column" will be used to refer both to a column in the data file and an entry in the `using` list.) For three columns, only `xerrorbars` (Note: xerrorbars ), `yerrorbars` (Note: yerrorbars ) (or errorbars), boxes, and `boxerrorbars` (Note: boxerrorbars ) are allowed. If another plot style is used, the style will be changed to `yerrorbars`. The `boxerrorbars` style will calculate the boxwidth automatically. For four columns, only `xerrorbars`, `yerrorbars` (or `errorbars`), `xyerrorbars` (Note: xyerrorbars ), `boxxyerrorbars` (Note: boxxyerrorbars ), and boxerrorbars are allowed. An illegal style will be changed to `yerrorbars`. Five-column data allow only the `boxerrorbars`, `financebars` (Note: financebars ), and `candlesticks` (Note: candlesticks ) styles. (The last two of these are primarily used for plots of financial prices.) An illegal style will be changed to `boxerrorbars` before plotting. Six- and seven-column data only allow the `xyerrorbars` and `boxxyerrorbars` styles. Illegal styles will be changed to `xyerrorbars` before plotting. For more information about error bars, please see `plot errorbars`.
