I don't think you can rotate the graph like you can in proc G3D.
You can however define blockmax= to change the vertical scale and make the blocks shorter so they don't hide other blocks.
Maybe another option if you use HTML output is to use the activex device and alter the HTML afterwards:
The activex parameters
g3dTilt="xx" g3dRotate="xx"
after
view2D="false"
are also supported for block outputs.
