label_properties — description of the Label entity properties
The Label entity is a child of an Axes entity. When an
Axes entity is built, the Title and Labels handles come with it and are
part of the Axes properties. Therefore, the properties of those
sub-objects are editable via the Axes handle (see gca and
gda). This entity defines the parameters for label
drawing:
This property contains the handle of the parent. The parent of the
label entity should be of type "Axes" .
Note that, for now, Label entity is exclusively used in
title, x_label, y_label and
z_label building.
This field contains the visible property value for
the entity . It should be "on" or "off" .By
default, the label is visible, the value's property is
"on". If "off" the label is not displayed on
the screen.
The matrix containing the strings of the object. The rows of the matrix are displayed horizontally and the columns vertically.
Starting from Scilab 5.2, it is possible to write LaTeX or MathML expression.
This field contains the color used to display the label
text. Its value should be a color index (relative to the
current colormap).
This field contains the color used to display the line around the box if any. Its value should be a color index (relative to the current colormap).
This field contains the color used to fill the box if any. Its value should be a color index (relative to the current colormap).
This field takes the values "on" or
"off". If "on" a box is draw around the text
with a line on its edge and a background.
Specifies the font used to display the label. This is a positive integer referecing one of the loaded fonts. Its value must be between 0, referecing the first font, and the number of loaded fonts minus one, referencing the last font. For more information see graphics_fonts.
It is a scalar specifying the displayed characters size.
If fractional_font property is "off"
only the integer part of the value is used.
For more information see graphics_fonts.
This property specify whether text is displayed using fractional font sizes.
Its value must be either "on" or "off".
If "on" the floating point value of font_size
is used for display and the font is anti-aliased. If "off" only the integer part is used
and the font is not smoothed.
This scalar allows you to turn the label. The font is turned
clockise with the angle given in degrees. Note that changing the
font_angle will automatically disable the
auto_rotation property.
If "on", Scilab computes automatically the best angle
to turn the label for the display. If "off", the label
can be manually turned with the font_angle property.
This 2d vector allows you to place manually the label on the
screen. The position is stored in the data units of the axes. Note
that changing the font_angle will automatically disable
the auto_position property.
If "on", Scilab computes automatically the best
position in the graphic window for the display. If "off",
the label can be manually places with the position
property.
