Re: ListPlot bug

I've seen this same problem with my computer. I use a Windows 98
computer and print with an HP Laser Jet 5si. The point does not appear
on the screen only when printed. That is, I was able to reproduce this
problem with the following inputs



produces a fine picture but

ListPlot[data, PlotStyle->AbsolutePointSize[5]]

produces a graphic that in addition to the data points has a extra point
at the top of the y-axis. I tried removing it by first increasing the
PlotRange and then using Show to decrease it


but the final graph still has the extra point on the y-axis when
printed. The only way I've been able to not get the extra point when
printing is to use


Has anyone else seen this problem and/or have a better solution to it?
