graphics with PSTric..

Note that with sufficiently many points specified in plotpoints, we getthe same curve with plotsyle=curve and plotstyle=line, since PostScriptdraws any curve by joining short enough line segments).There’s one more value plotstye=dots, which draws only the dots usedto draw the curve, without joining them. here, we can also use the variousdotstyle values described in the first chapter. This is shown in the nextexample:Plotting TricksFunction plottingAxes of coordinatesData plotting\begin{pspicture}(-2,-2)(2,2)\psgrid[gridcolor=Apricot,%gridlabelcolor=Mahogany,%subgridcolor=Apricot]\psplot[plotstyle=dots,%dotstyle=asterisk,%linecolor=Blue,%plotpoints=20]%{-1.5}{1.5}{x 3 exp x sub}\end{pspicture}210-1-2** *** ********** ***-2 -1 0 1 2**Online L A TEX TutorialPart II – GraphicsPSTricksOther relevant parameters can also be set for the \psplot command. Thusif we want to plot the function f (x) = sin x with x measured in radians (recallthat PostScript computes sin x for x measured in degrees), we will have toAscale down the x coordinates by˙180= 0.0174.
