Draw a series of connected geodesic curves
As with astCurve, full account is taken of the Mapping between physical and graphical coordinate systems. This includes any discontinuities and clipping established using astClip.
"
in"
array (which contains the input coordinates). This value is
required so that the coordinate values can be correctly located if they do not entirely
fill this array. The value given should not be less than "
npoint"
. "
[ncoord][indim]"
giving the physical coordinates of the points which are to be joined in sequence by
geodesic curves. These should be stored such that the value of coordinate number "
coord"
for point number "
point"
is found in element "
in[coord][point]"
. No curve is drawn on either side of any point which has any coordinate equal to the value AST__BAD.
An error results if the base Frame of the Plot is not 2-dimensional.
An error also results if the transformation between the current and base Frames of
the Plot is not defined (i.e. the Plot’
s TranInverse attribute is zero).
