I am trying to create a poster (right now I am using 'a0poster.cls') and I am not able to integrate subfigures overdrawn with tikz after this example by Gonzalo Medina. In this poster I am using also (externalized) pgfplots out of my thesis. The idea is to create a figure with three subfigures that are claryfied using interlinked arrows. I tried to find a way around my problem by externalizing the figure in a seperate .tex file to include the exported grapic subsequently, but here I also failed:

So my actual question is, what would be the best way to achieve my goal to integrate three subfigures decorated by arrows in a (a0) poster environment. Is there a workaround to integrate it directly with the mdwframed subfigures, or maybe an alternative?
