I'm trying to use GraphicsColumn to plot two curves with very different ranges. for example,
GraphicsColumn[{Plot[Sin[x], {x, 0, 10}, PlotRange -> All,
AspectRatio -> 0.3, Frame -> True, Axes -> False,
ImageMargins -> 20],
Plot[Cos[x], {x, 0, 10}, PlotRange -> All, AspectRatio -> 0.3,
Frame -> True, Axes -> False, ImageMargins -> 20]},
Epilog -> {Text["Frequency", {Center, Bottom}],
Rotate[Text["Power", {0.5, Center}], 90 Degree]}]
But the x label is not displayed properly, i.e., it is cut by the edge of the graph.
How to improve it?
