Function plottingAxes of coordinatesData plotting7. Plotting TricksWe have seen how we can join points to produce curves (for a mathematician,a line is also a curve!) with PSTricks, using such commands as \psline,\pspolygon, \pscurve, \psccurve and \psecurve. In all these commands,we’ll have to explicitly provide the coordinates of the points joined to make thecurve within the command itself. There are other methods of specifying thecoordinates, either implicitly as a mathematical equation or as data piped infrom another source. We discuss such tricks in this chapter.Online L A TEX TutorialPart II – GraphicsPSTricksE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.

7.1. Function plottingFor a mathematician, analytical geometry serves as a means of translationbetween algebra and geometry: an algebraic equation can be geometricallyrepresented as the curve joining the points with coordinates satisfying theequation (called the graph of the equation) (and on the other hand, a curve canbe algebraically represented as an equation specifying the relation betweenthe coordinates of the points on it).Thus for example, the graph of the equation y = x 3 − x for −1.5 ≤ x ≤ 1.5is as shown below:210Plotting TricksFunction plottingAxes of coordinatesData plottingOnline L A TEX TutorialPart II – GraphicsPSTricks-1-2-2 -1 0 1 2The package pst-plot contains the command \psplot to draw curves specifiedby such equations. (Throughout the following, we assume that thepackage pst-plot is loaded by the command \usepackage{pst-plot} in thepreamble.) The equation must be written in the PostScript Language.
