One other thought, when you set the Styles, (PlotStyle, fillstyle, etc) if you give a list, each item of the list applies a separate curve. In your original post, you had PlotStyle->{A,B}. This means that A applies to the first curve (although you had only one) and B applies to the second and subsequent curves. Directive will group various styles and apply them to one curve.

You need FillingStyle for the filling, not PlotStyle.
i.e.
ListPlot[m, LabelStyle -> {14, GrayLevel[0], Bold}, PlotStyle -> Blue, ImageSize -> 500, Filling -> Axis, FillingStyle -> Directive[Red, Thickness[.01]], PlotRange -> All]
Dear Neil,
Your help is always greatly appreciated.
Is possible to increase blue points size?
I found the solution.Thanks :)
