Ngl.text_ndc

Draws a text string on the viewport.

Prototype

txt = Ngl.text_ndc(wks, text, x, y, res=None)

Arguments

wks

The identifier returned from calling Ngl.open_wks.

text

The text string.

x, y

The NDC coordinates of the text string.

res=None

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

Return value

txt

A PlotId of the text object created.

Description

This procedure draws a text string on the viewport of the requested workstation. x and y are scalars defining the coordinates of the text string in NDC space, and resources can optionally contain an unlimited number of 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.

Missing values are not allowed in this procedure.
