This procedure is used to draw a polymarker using NDC units.
- An array of HLU plot objects.
- Either one HLU style object or an array with the
same dimensions as the objs parameter.
- The X coordinates of the polymarker in NDC units.
- The Y coordinates of the polymarker in NDC units.
NhlNDCPolymarker 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 NDC units. The coordinates are 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
