This is where \pscustom steps in.Look at the code and the output shown below:\begin{pspicture}(-1,-1)(1,0)\pscustom[fillstyle=solid,%fillcolor=Red,%linestyle=none]{%\psplot{-1}{0}{x 1 add 2 exp 1 sub}\psplot{0}{1}{x 1 sub 2 exp 1 sub}\psline(1,-1)(-1,-1)}\end{pspicture}Online L A TEX TutorialPart II – GraphicsPSTricksNow it’s only a question of scaling the stem we’ve created and pasting at thebottom of the circles, to make our picture:\psset{unit=1.5cm}\begin{pspicture}(-1,-1)(2,2)\bigdots(0,0)(0.8,0)(0.4,0.75)\rput(0.4,-0.3){%\pscustom[xunit=0.25cm,%yunit=0.75cm,%linestyle=none,%fillstyle=solid,%fillcolor=Red]{%\psplot{-1}{0}{x 1 add 2 exp 1 sub}\psplot{0}{1}{x 1 sub 2 exp 1 sub}\psline(1,-1)(-1,-1)}}\end{pspicture}•• •E Krishnan, CV Radhakrishnan and AJ Alexconstitute the graphics tutorial team.
