Getting viewport coordinates

Dear NCL Users,
        this may be a simple question. How to get the viewport coordinates of a
plot if the user does not set it explicitly through the resources to the
plotting function? For example, in a function which draws some objects,
I want to get the viewport coordinates to set the laberbar always at a
specified corner of the plot. The caller may not always specify the
vpHeightF etc parameters to this function.

Thanks in advance,

arindam
