Hi, If I plot something using ParametricPlot and later want to add something to the same plot, how is that done? Many thanks in advance, Sam Hi, It depends upon the thing you want to add and cannot be told apriori. However, if it is simply a graphics object you can do it by using Show. For example: This is a parametric plot from the Mathematica Help: pp=ParametricPlot[{Sin[u],Sin[2u]},{u,0,2Pi}]; This is an arrow to be added to the parametric plot: arr=Graphics[{Red, Arrow[{Scaled[{0.5,0.5}],Scaled[{0.9,0.9}]}]}]; And here they are added together. Show[{pp,arr}] Hope it helps. Alexei Alexei BOULBITCH, Dr., habil. IEE S.A.
