8.1. Simple customizationIf a certain graphics object in PSTricks is repeatedly used with some customparameter settings, we can save the tedium in typing in these values bysaving it under a new name. (This also comes in handy to make changes ina consistent manner, if we happen to change our mind later).8.1.1. New objectsYou may have noticed that many of our examples contain a colored grid likethe one below:\begin{pspicture}(-2,-2)(2,2)\psgrid[gridcolor=Apricot,%gridlabelcolor=Mahogany,%subgridcolor=Apricot]\psplot[plotstyle=curve,%linecolor=Blue]%{-1.5}{1.5}{x 3 exp x sub}\end{pspicture}-2 -1 0 1 2Since the same grid is used in all the examples, it’d be nice if we can avoid thetedium of typing all the parameter settings again and again; and its wherethe command \newpsobject comes in handy. Thus by defining\newpsobject{colgrid}%{psgrid}%{gridcolor=Apricot,%gridlabelcolor=Mahogany,%subgridcolor=Apricot}210-1-2Custom GraphicsSimple customizationHigher level customizationOnline L A TEX TutorialPart II – GraphicsPSTricksE Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.

we can use \colgrid every time we need the grid of these specifications.The syntax of the general command is:Custom GraphicsSimple customizationHigher level customization\newpsobject{name}%{object}%{parameter1=value1}%parameter1=value1. . . . . . . . . . . . }Where name is the name we give to the variant object (such as colgrid inthe example above), object is the name of the graphics object predefinedin PSTricks that we want to tweak (such as psgrid in the example) andParameter1, parameter2 are the parameters whose values we set by assigningvalues value1, value2 and so on.Once an object is defined using \newpsobject, we can change its parametersthe usual way by enclosing the new values within square brackets. Theexamples below illustrates this:Online L A TEX TutorialPart II – GraphicsPSTricks\newpsobject{bigdots}%{psdots}%{dotsize=1 0,%linecolor=Red}\begin{pspicture}(-0.5,-0.5)(1.5,1.37)\bigdots(0,0)(1,0)(0.5,0.866)\end{pspicture}\vspace{1cm}\begin{pspicture}(-0.5,-0.5)(1.5,1.37)\bigdots[linecolor=Green](0,0)\bigdots[linecolor=Blue](1,0)\bigdots(0.5,0.866)\end{pspicture}••••••E Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.
