PlotMarker differences in ListPlot between Mathematica 10.0.1 and Mathematica 10.1

    0}, {178, 1/1000}, {179, 1/500}, {180, 1/1000}};

Using the same code

ListPlot[data, PlotStyle -> Red, Filling -> Axis]

Mma 10.0.1 produces

enter image description here

and Mma 10.1 gives

enter image description here

As you can see, above plots are not identical. Since I favor the 10.0.1 version, I tried to make a modification in 10.1 by invoking PlotMarkers option and hoping I'll get more similar result.

ListPlot[data, PlotStyle -> Red, Filling -> Axis, PlotMarkers -> {Automatic, 8}]

The result is unsatisfactory.

enter image description here

Somehow, the plot is slightly moved to the left and the markers are not perfectly rounded. enter image description here

Is this an expected behavior from the newest version if Mma? Or, did I miss something?

You can look at the FullForm of the plots; the only difference is PointSize[0.009166666666666668]in version 10.1 andPointSize[0.01388888888888889`]in version 10.0.1. So you can take the plot from 10.1 and just dopl1 /. PointSize[0.009166666666666668`] -> PointSize[0.01388888888888889`]`. — b.gates.you.know.what, Jun 20 '15 at 09:56

The default PointSize in ListPlot seems to have changed between 10.0 and 10.1. You can match the version 10.0 appearance with

ListPlot[data, PlotStyle -> Directive[Red, PointSize[Medium]], Filling -> Axis]

Mathematica graphics

I seem to recall that PlotMarkers have always had issues with lining up properly.

In fact, this is because the default PlotMarkers are based on fonts instead of graphics primitives, and so their placement is in general less precise and also OS dependent, as discussed in the answers to this question: Point Renderings Slightly Off in Mathematica.

I would like to note that your idea to use the PlotMarkers option to fix your problem was not a bad one; you just needed a better value for the size.

ListPlot[data,
  PlotStyle -> Red, Filling -> Axis, PlotMarkers -> {Automatic, 6.5}]
