The marker size is configured with pointsize, ps or ms. Usually gnuplot identifies each marker type by a number, but Gaston provides some equivalent names (see Introduction to plotting. The marker type is configured with pointtype, pt or marker. The line color is set with lc or linecolor while the line width is specified with linewidth or lw. See all the details in gnuplot's documentation. Gnuplot supports many different plot styles for example, lines means plotting a line, points is just the markers, and linespoints is a line with markers. The plot style is set with the keys w, with, or plotstyle. Set the plot style, line color, line pattern, line width, and markers Use set(debug = false) to turn this mode off. If you want to see exactly what commands Gaston is sending to gnuplot, you can turn on debug mode: set(debug = true) (Some of the examples below are taken from lazarusa's excellent gallery). However, Gaston provides a few specialized commands that make certain plots easier. The plot command has enough flexibility to plot everything that Gaston is capable of. It accepts the same arguments as plot, except for Axes() arguments, which can only be set from plot. To add a new curve to an existing figure, use plot!. The special keyword axesconf is used to provide a string with commands that are passed literally to gnuplot. Essentially, anything that can be set in gnuplot, can be configured from Gaston by wrapping it in Axes().
Note that, instead of using a bunch of individual keyword arguments, you can pass gnuplot a complete plot command using the keyword curveconf.Īxeskwargs is a set of keyword arguments wrapped in Axes(), which specify the look of the axes, or figure this refers to things like the plot title, tics, ranges, grid, etcetera. These arguments are used to build a plot command for gnuplot.
These typically specify the plot style, the line color, the marker type, etcetera. Gaston translates the provided data to the format that gnuplot requires, and writes it to a temporary file.Ĭurvekwargs is a set of keyword arguments that are related to the appearance of the plotted data. supp is a keyword argument used for supplementary data, which are additional columns that gnuplot can use, such as the errorbar length, or the marker size. For most plots, vectors are plotted, but plotting images requires a matrix or 3-D array. Basics of plottingĪ call to plot looks like this: plot(x, y, z, supp, curvekwargs., Axes(axeskwargs.))
