Hi, Sjoerd,
I agree with you. I think this is one of the cases where Mathematica's defaults work pretty well for one plotting task, and perhaps less well for another. Of course, by explicitly putting in an AxesOrigin and PlotRange for a 2D plot, one can get the same behavior as in 3D plots. So the behavior is at least somewhat consistent between the 2D and 3D cases.
Plot[Sin[x] + 2, {x, -3, 3}, AxesOrigin -> {0, 0},
PlotRange -> {1, 3}]
Regards,
Curtis
