1.2. Drawing DotsNow let’s see how to draw pictures with PSTricks. The basic package touse is pstricks and so we assume in all the codes given below that thispackage has been loaded with the command \usepackage{pstricks} inthe document preamble.Let’s start with the simplest of graphical objects—a single dot. Type inthe code below in your document:Graphics with PSTricksGetting the pointsDrawing DotsSimple LinesEnds of LinesBent Lines and PolygonsSimple CurvesLook at this dot \psdots(1,0)and T E X compile the document. To produce the PostScript, you’ll have touse the dvips program or any other dvi to PostScript translator available inyour system. With dvips, this done by the commanddvips filename -owhere filename is the name of your file without any extension (or with theextension .dvi). This creates a PostScript file of the same name but withthe extension .ps which you can view using a PostScript previewer, such asghostview. It looks like this:Online L A T E X TutorialPart II – GraphicsLook at this dotSome explanations are in order. Evidently the command to draw a dotis \psdots followed by the coordinates of the point where the dot is to beplaced. But we know that the assignment of coordinates to points (and viceversa) makes sense only after fixing the axes. So when we specify coordinatessuch as (0,1) as above, what are the axes used? By default, PSTricksuses the current point in T E X as the origin and horizontal and vertical linesthrough this point as the axes. Again, the default unit is 1 cm. Thus in theabove example, a point is drawn 1 cm. away from the letter t in dot.
