text properties

description of the Text entity properties


The Text entity is a leaf of the graphics entities hierarchy. This entity defines the parameters for string drawing


This property contains the handle of the parent. The parent of the text entity should be of the type "Axes" or "Compound".


This property contains a vector with the children of the handle. However, text handles currently do not have any children.


This field contains the visible property value for the entity . It should be "on" or "off" .By default, the text is visible, the value's property is "on". If "off" the text 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.


Specify how the strings are aligned in their columns. The value must be 'left','center'or 'right'.


This field is the vector [x,y,[z]] of the origin of the text in the data units of the axes.


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.


This boolean property allows to draw or not a line around the box when the box property is "on". If line_mode is "off", the line of the box is not drawn.


This boolean property allows to draw or not the background of the box when the box property is "on". If fill_mode is "off", the background of the box is not transparent.


A two dimensional vector specifying the size of a rectangle in user coordinates. The rectangle is used when the text_box_mode property is set to 'centered' or 'filled'.


May have three different value : 'off', 'centered' or 'filled'. If 'off', the strings are displayed using the given font and the data field specifies the position of the lower-left point of the text. If 'centered', the text is displayed in the middle of the rectangle whose size is given by text_box. If 'filled' the font size of the strings will be expanded to fill the rectangle.

When using 'off' or 'centered' modes, text size remains constant upon zooming. They are the best modes to create annotations in a graph. On the contrary, when using the 'filled' mode, the text size follow the graphic scale. It is then possible to zoom upon text objects.


auto_dimensionning set to "off" is equivalent to text_box_mode set to "filled". If text_box_mode is "off" or "centered" then it implies that auto_dimensionning is "on".


This field contains the color used to display the characters of the text. Its value should be a color index (relative to the current colormap).


This field contains the color used to display the line on the edge of the box. Its value should be a color index (relative to the current colormap).


This field contains the color used to fill the box around of the text. Its value should be a color index (relative to the current colormap).


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.


Specifies the font used to display the character strings. 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.


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 property determines the orientation of the text string. Specify value of rotation in degrees.


This field contains the clip_state property value for the text. Its value should be :

  • "off" this means that the text is not clipped.

  • "clipgrf" this means that the text is clipped outside the Axes box.

  • "on" this means that the text is clipped outside the rectangle given by the property clip_box.


This field contains the clip_box property. Its value should be an empty matrix if clip_state is "off" or the vector [x,y,w,h] (upper-left point width height).


This field can be use to store any scilab variable in the text data structure, and to retreive it.
