I often seek to display two graphs, side by side, with a common label over them. There is no option for adding a label to GraphicsRow, which means, I think, that I need to use Grid or GraphicsGrid and include a row on top that has SpanFromLeft set to allow a graphically defined line of text occupy the entire row.

It seems like a lot of work to do something simple. Is there a better solution?

    $\begingroup$ You can use Labeled $\endgroup$ – rm -rf♦ Sep 24 '13 at 0:07

Possibly more versatile, but you have to mess with text overlapping your plots, but GraphicsRow also accepts Epilog

GraphicsRow[{Plot[Sin[x], {x, 0, 4 Pi}], Plot[Cos[x], {x, 0, 4 Pi}]}, 
 Spacings -> Scaled[0.4], 
 Epilog -> Inset["Plot Title", Scaled[{0.5, 0.95}]]]

Mathematica graphics

    $\begingroup$ PlotRangePadding -> {0, {0, 25}} could help avoid possible text/plot collisions. $\endgroup$ – ssch Sep 24 '13 at 0:24
  • $\begingroup$ @ssch Thanks - I figured there was a padding option, but couldn't put my finger on it. $\endgroup$ – bobthechemist Sep 24 '13 at 0:26

GraphicsRow takes a PlotLabel option:

p1 = Plot[Sin[x], {x, 0, Pi}, PlotLabel -> Sin];
p2 = Plot[Cos[x], {x, 0, Pi}, PlotLabel -> Cos];
GraphicsRow[{p1, p2}, PlotLabel -> "Two plots"]

    $\begingroup$ @MichaelStern Easy to miss since it's not in the GraphicsRow documentation :) $\endgroup$ – ssch Sep 24 '13 at 0:38

    $\begingroup$ @Michael Indeed, this is the first time I can recall seeing this, so thank you for asking the question! (+1 of course, ssch) $\endgroup$ – Mr.Wizard Sep 24 '13 at 0:50

When I need more interface control, I usually do something like this:

p1=Plot[Sin[x],{x,0,Pi},PlotLabel->Sin,ImageSize->150];
p2=Plot[Cos[x],{x,0,Pi},PlotLabel->Cos,ImageSize->150];
title=Panel[Style["Test Label",White,20],ImageSize->300,Background->Orange,Alignment->Center];
Deploy@Grid[{{title,SpanFromLeft},{p1,p2}},Dividers->Gray,Spacings->{0,0}]

Few additional methods:

p1 = Plot[Sin[x], {x, 0, 2 Pi}, ImageSize -> 200];
p2 = Plot[Cos[x], {x, 0, 2 Pi}, ImageSize -> 200];

Labeled

Labeled[Panel@GraphicsRow[{p1, p2}], Style["Label", "Subsubsection"], Top] // Panel

enter image description here

Panel

Panel[GraphicsRow[{p1, p2}], Style["Label", "Subsubsection"], Top] // Panel
(* same picture *)

Legended

Legended[Panel@GraphicsRow[{p1, p2}], Placed[Style["Label", "Subsubsection"], Top]] // Panel
(* same picture *)

Show with PlotLabel

Show[GraphicsRow[{p1, p2}],  PlotLabel -> Style["Label", "Subsubsection"]] // Panel
