I tried bar(1), which produces a blue bar for ML R2011b and an green one for 
Octave (tip: 99cd136079f7).

For Matlab I see ...

        CData = [1;1;1;1]
        CDataMapping = 'scaled'
        FaceColor = 'flat'

With clim = [1 2] for the axes.

and for Octave ...

        cdata = 0
        cdatamapping = 'scaled'
        facecolor = 'flat'

With clim = [-1 1] for the axes.

The climmode for both Octave and Matlab is set to "auto".
