I changed the Subject heading to reflect the topic. Here is a sample set of points. pts = Table[{x, Sin[x]}, {x, 0, Pi, Pi/16}]; You can adjust the point size by using the Prolog option in ListPlot. ListPlot[pts, Prolog -> AbsolutePointSize[4]]; You can also plot your points this way, without using ListPlot. Show[Graphics[{AbsolutePointSize[4], Point /@ pts}], Frame -> True]; You can plot the points with whatever symbol you wish by using routines from the MultipleListPlot package. The following plots the points as stars. Needs["Graphics`MultipleListPlot`"] Needs["Graphics`Colors`"] Show[Graphics[ {PlotSymbol[Star, 5] /@ pts}], Frame -> True]; You can even make up your own symbols using the MakeSymbol command. This makes a black cross with a Blue dot in the center. Show[Graphics[{MakeSymbol[{Blue, AbsolutePointSize[6], Point[{0, 0}], Black, Line[{{1, 1}, {-1, -1}}*6], Line[{{-1, 1}, {1, -1}}*6]}] /@ pts}], Frame -> True, ImageSize -> 500]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ > From: Au Han Bin [mailto:auhb3 at cz3.nus.edu.sg] To: mathgroup at smc.vnet.net > > > i'd like to ask if i can make the dots for ListPlot bigger, or preferably > change it to other symbols or shapes? > desperately needing help > > regards, joshua_au at hotmail.com >
