NhlGetBB
This function is used retrieve the bounding boxes of a list of HLU
input objects. (See NhlGetBB.)
Synopsis
function NhlGetBB(
objs[*]:graphic
)
Arguments
- objs
- List of HLU View instances from which bounding boxes are requested.
Description
The HLU version of this returns a data structure containing the top, bottom,
left, and right NDC units of a View instance. In NCL, this function returns
an array of the four coordinates. Index 0 contains the top coordinate, 1
contains the bottom, 2 contains the left, and 3 contains the right. If more
than one View instance is passed in in the objs array. The return array
is dimensioned [n]x[4] where n is the number of View instances in the objs
parameter. If any element of the objs parameter is not a valid
plot, the four bounding box elements associated with its index will be assigned
the integer default missing value.
