I have been puzzling over the interactions between ImageSize, Frame, various paddings, etc., and found what appears as inconsistent behavior of such options. Consider the 2x2 array of plots produced by this code: (Mathematica v9 or v8) Clear[f, i3, g, d3]; d3 = {{{2012, 1, 1}, 1}, {{2012, 2, 1}, 2}, {{2012, 3, 1}, 3}}; i3 = d3[[All, 2]]; Print["d3=", d3 // MatrixForm, " i3=", i3]; f[b_] := ListPlot[i3, Frame -> b] // Framed; g[b_] := DateListPlot[d3, Frame -> b] // Framed; {{f[True], f[False]}, {g[True], g[False]}} Three of the four results are the same size; the lower right result is smaller than the others: It seems that applying a Frame, or not, does not change the size of a plot produced by ListPlot, but does change the size of a plot produced by DateListPlot. I seek an explanation for this behavior.
