Thick of a marker in ErrorListPlot

Question

I have error bars that are too small, so the marker are too big, i want to shrink the dots. If i do ErrorListPlot[dato,PlotMarkers->{o,1}] my bars do not show, but if i do ErrorListPlot[dato,PlotStyle->Thin] it draw the bars thin but the dot remains too big. What can i do?

Answer 1

You can set a point size in PlotStyle:

ErrorListPlot[Table[{i, RandomReal[0.5]}, {i, 5}], PlotStyle -> AbsolutePointSize[4]]

See belisarius's answer for full control using post-processing.

Answer 2

You can change the point style like this:

SeedRandom[42];
ErrorListPlot[Table[{i, RandomReal[0.5]}, {i, 5}]] /. 
   Point[a__] :> {Red, PointSize[#], Point[a]} & /@ {.008, .1}
