Hello, It seems that I have found one very important statement on the Documentation page for PlotMarkers which is inconsistent with real behavior of this option. On the page http://reference.wolfram.com/mathematica/ref/PlotMarkers.html under "More information" we read: "With PlotMarkers->{g,s}, the object g is scaled so that one unit of its coordinates corresponds to a fraction s of the width of the whole graphic." Let us see how in really this option works. There are at least two inconsistent cases: 1a) When using characters as PlotMarkers: In[20]:= Cases[ ListPlot[{1, 1}, PlotMarkers -> {"\[HappySmiley]", .1}], x_Inset :> InputForm[x], Infinity] Out[20]= {Inset[Style["\[HappySmiley]", FontSize -> 0.1], 3], Inset[Style["\[HappySmiley]", FontSize -> 0.1], 4]} One can see that the size of the character "\[HappySmiley]" is completely independent from the width of the whole graphics. Moreover, it is doubtful that this can be properly fixed by replacing FontSize - > 0.1 by FontSize -> Scaled[0.1] since (as fas as I know) font scaling is not completely smooth (I can be wrong here). What is the simplest workaround for this (I think that we probably should scale entire Inset instead of using the FontSize option)? This bug is very annoying. 2b) When using Graphics as PlotMarkers: In[24]:= Cases[ ListPlot[{1, 1}, PlotMarkers -> {Graphics@Circle[{0, 0}, 1], 0.1}], x_Inset :> InputForm[x], Infinity] Out[24]= {Inset[Graphics[Circle[{0, 0}, 1]], 3, Automatic, Scaled[{0.1, 0.1}]], Inset[Graphics[Circle[{0, 0}, 1]], 4, Automatic, Scaled[{0.1, 0.1}]]} One can see that the size of the Graphics is scaled not only with the width of the plot but also with its height. I think that this behavior is right and so the Documentation needs to be corrected. P.S. I use Mathematica 7.0.1
