From Kristofer Tingdahl, "the vertical bar is upside down, and hence not as the documentation says it should be. This is corrected with this patch"

Browse Source 
From Robert Osfield, changed the example so that the vertical and horizon scalar bars are rotated to the XZ plane so you can see them with the default viewer's camera orientation.
Tweaked the positioning of title text of vertic scalar bar to avoid overlap of text.
