This procedure is used to draw a polymarker using data coordinates.
- An array of HLU plot objects.
- Either one HLU style object or an array with the same
dimensions as the objs parameter.
- The X data coordinates of the polymarker in data coordinates.
- The Y data coordinates of the polymarker in data coordinates.
NhlDataPolymarker draws the polymarker defined by the pair
of vectors x and y using either a single style object or the corresponding style object from the style
parameter. The vectors x and y contain values in data
coordinates. The coordinates are mapped using the HLU object's
data transformation and drawn as a polymarker clipped to the viewports
of each HLU plot object in
the objs array. The difference between the NCL version and the HLU
version is that the NCL version draws the polymarker
over one or more HLU plot objects using one or more styles, and
the NCL version does not need the length of the x
and y parameters because this information is inherent
in NCL data. In the HLU version, NULL can be used to use the
default graphic style object. In NCL, however, the default style object
must be retrieved from the workstation parent using the
resource and the
