![]() ![]() The special filenames "" and "-" are permitted, as in plot. Splot, like plot, can display from a file. See also show plot, set view map, and sampling. The datafile options have more differences.Īs an alternative to surfaces drawn using parametric or function mode, the pseudo-file '++' can be used to generate samples on a grid in the xy plane. The operation of with is also the same as in plot except that not all 2D plotting styles are available. In non-parametric mode, ranges must be given in the order splot. The syntax for setting ranges on the splot command is the same as for plot. See set view and set xyplane for more information. The orientation of a splot projection is controlled by set view. The offset between the lowest ztic and the xy plane can be changed by set xyplane. The function can be a mathematical expression, or a triple of mathematical expressions in parametric mode.īy default splot draws the xy plane completely below the plotted data. Data file names are usually provided as a quoted string. The splot command operates on a data generated by a function, read from a data file, or stored previously in a named data block. See the plot command for many options available in both 2D and 3D plots. splot provides only a single x, y, and z axis there is no equivalent to the x2 and y2 secondary axes provided by plot. It is the 3D equivalent of the plot command. ![]() Splot is the command for drawing 3D plots (well, actually projections on a 2D surface, but you knew that).
