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 or splot command or will be chosen sequentially from the types available to the terminal in use. Use the command test to see what is available.
None of the errorbars styles can be used with splots or function plots. If one is specified, it will be changed to points.
For 2-d data with more than two columns, gnuplot is picky about the allowed errorbar styles:
For three columns, only xerrorbars, yerrorbars (or errorbars), boxes, and 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, boxxyerrorbars, and boxerrorbars, are allowed. An illegal plot style will be changed to yerrorbars.
Five-column data allow only the boxerrorbars style. 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.
Use the using option on the plot command to set up the correct number of
columns for the style you want.
