>From what I can see it is not possible with heatmap.2. If you are looking for a function that can create a heatmap with a color legend, you can try function image.plot in the package fields, or the function labeledHeatmap in the package WGCNA. Neither of them has the histogram-enhanced color legend, but labeledHeatmap definitely takes an argument zlim which you can set to say c(-1, 1) to obtain a consistent color scale, and the last time I used image.plot (which was quite some time ago), that function also took that argument. See examples listed in help(labeledHeatmap) for a few examples of what it can do.
