Aligning Plots in V6

A question yesterday about plotting in Do loops and the answers do it got me to exploring the example a little more. A common complaint in pre Version 6 graphics was the difficulty in aligning vertical plots on the x axes of the two plots. With new commands like GraphicsColumn and ImagePadding V6 makes this much easier. The alignment problem usually occurs when the ticks values and labels outside of the plot frame take up different spaces. By using ImageMargin to allow for sufficient space for each of the plots the problem is solved. ImageMargins are in printer points and may be specified for all sides of a plot. They must leave enough room for tick labels, frame labels and plot labels. For alignment you need the same ImageMargins for each plot. Here is an example where the bottom plot has longer y tick values, and a y frame label that takes more space. Labeled[ GraphicsColumn[ Table[Plot[10^(2 n) Sin[x], {x, 0, 2*Pi}, Frame -> True, FrameLabel -> {x, function/n}, PlotLabel -> 10^(2 n) Sin[x], ImagePadding -> {{80, 15}, {35, 25}}, Background -> ColorData["Legacy", "Linen"]], {n, 1, 2}], Center, {{20, 20}, {20, 5, 20}}, Background -> LightGreen, ImageSize -> 500], "Aligning Two Plots", {{Bottom, Left}}] I added extra elements to the plot that a user might typically use. The plots appear to be aligned whether Left, Center, Right or Automatic is used for the GraphicsColumn alignment. The only small problem I find is that right hand side horizontal spacing after the plots seems to be slightly off and difficult to control exactly.
