-
Text.anchor¶ Anchor location for a
text object.Type: TextAnchorSpecify the anchor point, or fixed point, for the text object. As the text object grows or shrinks, the anchor location is fixed, while the rest of the box adjusts to accommodate the new size. (default =
TextAnchor.Left)There are nine possible anchor position points, corresponding to the left, right, and center positions on the headline, midline, and baseline of the text box.
Example showing how to set the anchor of a
text object:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text('abc') >>> text.anchor = TextAnchor.Center >>> text.anchor TextAnchor.Center
-
Text.anchor_position¶ Anchor coordinate position (e.g., origin) of the Annotations.
Type: 2- tupleoffloatsThis will be \((x,y)\) or \(( heta,r)\) depending on the plot type (Cartesian or polar). This example shows how to set the anchor position of a
Textobject:>>> import tecplot as tp >>> text = tp.active_frame().add_3d_text("abc") >>> text.anchor_position = (1.0, 2.0) >>> text.anchor_position.x 1.0 >>> text.anchor_position.y 2.0
-
Text.angle¶ Angle of the text box in degrees.
Type: float(degrees counter-clockwise)The text angle is the orientation of the text relative to the axis. The angle is measured in degrees counter-clockwise from horizontal. Horizontal text is at zero degrees; vertical text is at 90 degrees.
Example showing how to set the angle of a
text object:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.angle = 45 >>> text.angle 45.0
-
Text.attached¶ Attach the Annotations to a specific Zone or map.
Type: boolean(default: False)Example showing how to set the attached property of of a
Textobject:>>> import tecplot as tp >>> text = tp.active_frame().add_text("abc") >>> text.zone_or_map = 1 >>> text.attached = True >>> text.zone_or_map 1 >>> text.attached True
-
Text.bold¶ Use bold typeface in the
text object.Type: booleanExample showing how to set the bold property of a
text object:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.typeface = 'Times' >>> text.bold = True >>> text.bold True
-
Text.clipping¶ Clipping properties of the Annotations
Type: Clipping(default:Clipping.ClipToViewport)Clipping refers to displaying only that portion of an object that falls within a specified clipping region of the plot. If you have specified your text position in the Frame coordinate system, the Annotations will be clipped to the frame.
If you have specified the Grid coordinate system, you can choose to clip your Annotations to the frame or the viewport. The size of the viewport depends on the plot type as follows:
- 3D Cartesian - The viewport is the same as the frame, so viewport
- clipping is the same as frame clipping.
- 2D Cartesian/XY Line - The viewport is defined by the extents of
- the X and Y axes.
- Polar Line/Sketch - By default, the viewport is the same as the
- frame.
Example showing how to set the clipping of a
Text:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text('abc') >>> text.clipping = Clipping.ClipToFrame >>> text.clipping Clipping.ClipToFrame
-
Text.color¶ Colorof the Annotations.Type: Color(default:Color.Black)Example showing how to set the
Colorof of aTextobject:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text("abc") >>> text.color = Color.Blue >>> text.Color Color.Blue
-
Text.italic¶ Use italic typeface of the
text object.Type: booleanExample showing how to set the italic property of a
text object:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.typeface = 'Times' >>> text.italic = True >>> text.italic False
-
Text.line_spacing¶ Spacing between lines in the text box.
Type: float(default = 1.0)Line spacing is dependent on the height of the text and the size unit system in which it is drawn. This example shows how to set the line spacing of a
text object:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.line_spacing = 4 >>> text.line_spacing 4.0
-
Text.position_coordinate_system¶ Position coordinate system of the
text object.The text object may be positioned using either the grid coordinate system or the frame coordinate system.
If the position_coordinate_system is
CoordSys.Frame, then the size_units property must beUnits.FrameorUnits.Point.The text object’s position and text height are adjusted so that it remains identical to its visual appearance in the original coordinate and unit system.
Type: CoordSys, must be eitherCoordSys.FrameorCoordSys.GridIf the size units are
Units.Gridand the position coordinate system is changed toCoordSys.Frame, then the size units will be changed toUnits.Frame. (default = CoordSys.Frame)Example showing how to set the position coordinate system for a
text object:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text("abc") >>> text.position_coordinate_system = CoordSys.Grid >>> text.position_coordinate_system CoordSys.Grid
Example showing side effect if size units are
CoordSys.Gridand the coordinate system is changed toCoordSys.Frame:>>> import tecplot as tp >>> text = tp.active_frame().add_text("abc") >>> text.size_units = Units.Grid >>> text.size_units Units.Grid >>> # Setting the coord sys to frame will change units to frame. >>> text.position_coordinate_system = CoordSys.Frame >>> text.position_coordinate_system CoordSys.Frame >>> text.size_units Units.Frame
-
Text.scope¶ The
Scope(local or global) of the Annotations.Type: ScopeAnnotations with local scope are displayed only in the
framein which they are created. If the annotation is defined as havingglobalscope, it will appear in all “like”frames. That is, those frames using the same data set as the one in which the annotation was created. (default:Scope.Local)Example showing how to set the scope of a
Textobject:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text("abc") >>> text.scope = Scope.Global >>> text.scope Scope.Global
-
Text.size¶ The text size in the currently defined text size units.
Type: integerExample showing how to set the text size of a
text object:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text('abc') >>> text.size_units = Units.Point >>> text.size = 14 >>> text.size 14
-
Text.size_units¶ Units of the text character height.
Type: UnitsUnitsmay be one of the following:Units.Point: Specify character height in points.Units.Frame: Specify character height as a percentage of frame- height
Units.Grid: Specify character height in grid units.
(default =
Units.Point)- Notes::
- One point is 1/72nd of an inch.
Units.Gridis available only if position_coordinate_system isCoordSys.Grid
- The position coordinate system will be changed to
CoordSys.Grid - if size units is set to
Units.Grid
- The position coordinate system will be changed to
Example showing how to set the units of the character height for a
text object:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text("abc") >>> text.position_coordinate_system = CoordSys.Grid >>> text.size_units = Units.Point >>> text.size_units Units.Point
-
Text.text_box¶ The
text.TextBoxobject for thisTextobject.The text box is a box that is drawn around the text. Note that in order to show the text box, you must set TextBox.type to a value other than TextBox.None.Type: text.TextBoxNote
This property is read-only.
Example showing how to enable the text box for a
text object:>>> import tecplot as tp >>> from tecplot.constant import * >>> text = tp.active_frame().add_text("abc") >>> text.text_box.type = TextBox.Filled # Show the text box
-
Text.text_string¶ The text to be displayed in a text box.
Type: stringYou can embed Greek, Math, and User-defined characters into English-font strings by enclosing them with text formatting tags, together with the keyboard characters.
The text formatting tags and their effects are as follows. Format tags are not case sensitive and may be either upper or lower case:
- <b>…</b> - Boldface
- <i>…</i> - Italic
- <verbatim>…</verbatim> - Verbatim
- <sub>…</sub> - Subscripts
- <sup>…</sup> - Superscripts
- <greek>…</greek> - Greek font.
- <math>…</math> - Math font.
- <userdef>…</userdef> - User-defined font.
- <helvetica>…</helvetica> - Helvetica font.
- <times>…</times> - Times font.
- <courier>…</courier> - Courier font.
Not all fonts have Bold and/or Italic variants. For fonts that do not have these styles, the <b> and/or <i> tags may have no effect.
Embedding and escaping special characters work only in English-font text; they have no effect in text created in Greek, Math, or User-defined character sets.
You can produce subscripts or superscripts by enclosing any characters with <sub>…</sub> or <sup>…</sup>, respectively. Tecplot 360 has only one level of superscripts and subscripts. Expressions requiring additional levels must be created by hand using multiple text objects. If you alternate subscripts and superscripts, Tecplot 360 positions the superscript directly above the subscript. To produce consecutive superscripts, enclose all superscript characters in a single pair of tags.
To insert a tag into text literally, precede the first angle bracket with a backslash (“”). To insert a backslash in the text, just type two backslashes (“”). This example shows how to set the text string of a
text object:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.text_string 'abc' >>> text.text_string ='def' >>> text.text_string 'def'
-
Text.typeface¶ The font family used by the
Textobject.Type: stringFor consistency across various platforms, Tecplot 360 guarantees that the following standard typeface names are available:
- “Helvetica”
- “Times”
- “Courier”
- “Greek”
- “Math”
- “User Defined”
Other typefaces may or may not be available depending on the TrueType fonts available. If the typeface or style is not available, a suitable replacement will be selected. This example shows how to set the typeface of a
text objectto ‘Times’:>>> import tecplot as tp >>> text = tp.active_frame().add_text('abc') >>> text.typeface = 'Times' >>> text.typeface 'Times'
-
Text.zone_or_map¶ Zero-based index to the zone or map of this Annotations.
Type: IndexExample showing how to set the zone or map
Indexof aTextobject:>>> import tecplot as tp >>> text = tp.active_frame().add_text("abc") >>> text.zone_or_map = 1 >>> text.zone_or_map 1
