You could use the Symbol or MakeSymbol commands from the MultipleListPlot standard package. DrawGraphics has CirclePoint[location, absolutesize, rimcolor, diskcolor] that makes nice looking points for plotting. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: AES/newspost [mailto:siegman at stanford.edu] To: mathgroup at smc.vnet.net Are there any simple or easy ways to substitute a user-defined symbol, especially a "filled" symbol, for the Points in a ListPlot or Epilog? The data I want to plot is already created in lengthy lists of the form pointData = { {x1,y1}, {x2,y2}, . . . . . } which I can plot directly by using ListPlot or by putting Map[Point, pointData] into an Epilog. I suppose I could create filled circles to replace the Points in this Epilog, for example, by using something like Epilog->{White, Map[Disk, convertedPointData], Map[Circle, convertedPointData]} so that the filled opaque circles would overlay and hide the theoretical data lines that pass underneath them. Trying to convert my pointData lists into the necessary form so that I can do this has proven to be a frustrating exercise, however. So, is there a way to do this list conversion so that Disk and Circle will Map onto the resulting list? -- or, a way to redefine the point symbol in Point to be something more complex? (Having gotten used to the joys of Stroke and Fill in Illustrator, I'm frustrated that Mathematica doesn't seem to offer -- or I haven't been able to find -- similar graphical constructs.)
