Point Renderings Slightly Off in Mathematica
I'm using the ErrorListPlot function in the ErrorBarPlots package. I want to display markers and the error bars, however, the marker appears to be shifted slightly to the left of the error bars. I'm not sure which is actually at the correct position. I'm using Mathematica 8.0.4 on Windows 7.
Example Code:
ErrorListPlot[{{5, 1}}, PlotMarkers -> Automatic]
Image illustrating the problem:

Using ErrorBar as such:
ErrorListPlot[{{{5, 1}, ErrorBar[1]}}, PlotMarkers -> Automatic]
doesn't solve the problem.
