l_layer_text: Layer a text

In loon: Interactive Statistical Data Visualization

Layer a text

Description

Loon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.

layer a single character string

Usage

l_layer_text(
  widget,
  x,
  y,
  text,
  color = "gray60",
  size = 6,
  angle = 0,
  label = "text",
  parent = "root",
  index = 0,
  ...
)

Arguments

widget	widget path name as a string
x	coordinate
y	coordinate
text	character string
color	color of text
size	size of the font
angle	rotation of text
label	label used in the layers inspector
parent	group layer
index	of the newly added layer in its parent group
...	additional state initialization arguments, see l_info_states

Details

As a side effect of Tcl's text-based design, it is best to use l_layer_text if one would like to layer a single character string (and not l_layer_texts with n=1).

For more information run: l_help("learn_R_layer")

Value

layer object handle, layer id
