# Graphics Primitives for Text

With the Text graphics primitive, you can insert text at any position in two- or three-dimensional Mathematica graphics. Unless you explicitly specify a style or font using Style, the text will be given in the graphic's base style.

 Text[expr,{x,y}] text centered at the point Text[expr,{x,y},{-1,0}] text with its left-hand end at Text[expr,{x,y},{1,0}] right-hand end at Text[expr,{x,y},{0,-1}] centered above Text[expr,{x,y},{0,1}] centered below Text[expr,{x,y},{dx,dy}] text positioned so that is at relative coordinates within the box that bounds the text Text[expr,{x,y},{dx,dy},{0,1}] text oriented vertically to read from bottom to top Text[expr,{x,y},{dx,dy},{0,-1}] text that reads from top to bottom Text[expr,{x,y},{dx,dy},{-1,0}] text that is upside-down

Two-dimensional text.

This generates five pieces of text, and displays them in a plot.
 Out[1]=
Here is some vertically oriented text with its left-hand side at the point .
 Out[2]=

When you specify an offset for text, the relative coordinates that are used are taken to run from to in each direction across the box that bounds the text. The point in this coordinate system is defined to be center of the text. Note that the offsets you specify need not lie in the range to .

Note that you can specify the color of a piece of text by preceding the Text graphics primitive with an appropriate RGBColor or other graphics directive.

 Text[expr,{x,y,z}] text centered at the point Text[expr,{x,y,z},{sdx,sdy}] text with a two-dimensional offset

Three-dimensional text.

This puts text at the specified position in three dimensions.
 Out[3]=

Note that when you use text in three-dimensional graphics, Mathematica assumes that the text is never hidden by any polygons or other objects.

 option name default value Background None background color BaseStyle {} style or font specification FormatType StandardForm format type

Options for Text.

By default the text is just put straight on top of whatever graphics have already been drawn.
 Out[4]=
Now there is a rectangle with the background color of the whole plot enclosing the text.
 Out[5]=
