Ngl.polymarker_ndc

Draws polymarkers on the viewport.

Prototype

Ngl.polymarker_ndc(wks, x, y, res=None)

Arguments

The identifier returned from calling Ngl.open_wks.

Scalars, one-dimensional NumPy arrays, or Python lists containing the x, y NDC coordinates of the polymarkers.

An (optional) instance of the Resources class having GraphicStyle resources as attributes.

Return value

Description

This procedure draws polymarkers on the viewport of the requested workstation. x and y are 1-dimensional arrays (these can be Python lists or tuples, or NumPy arrays) defining the coordinates of the polymarkers in NDC space, and resources can optionally contain an unlimited number of GraphicStyle attributes that are resource names and their values.

The frame is not advanced when you call this procedure, so you need to call Ngl.frame yourself if you want to advance the frame.

There is no automatic handling of fill values. See the FAQ, How do I set a missing value for my data?
