<h4 class="subsection">15.2.8 Use of the <code>interpreter</code> Property</h4>
<a name="XREFinterpreterusage"></a>
<p>All text objects—such as titles, labels, legends, and text—include
the property <code>"interpreter"</code> that determines the manner in
which special control sequences in the text are rendered.
</p>
<p>The interpreter property can take three values: <code>"none"</code>, <code>"tex"</code>,
<code>"latex"</code>. If the interpreter is set to <code>"none"</code> then no special
rendering occurs—the displayed text is a verbatim copy of the specified text.
Currently, the <code>"latex"</code> interpreter is not implemented and is equivalent
to <code>"none"</code>.
</p>
<p>The <code>"tex"</code> option implements a subset of TeX functionality when
rendering text. This allows the insertion of special glyphs such as Greek
characters or mathematical symbols. Special characters are inserted by using
a backslash (\) character followed by a code, as shown in <a href="#tab_003aextended">Table 15.1</a>.
</p>
<p>Besides special glyphs, the formatting of the text can be changed within the
string by using the codes
</p>
<table>
<tr><td width="20%"></td><td width="20%">\bf</td><td width="60%">Bold font</td><td width="20%"></td></tr>
<tr><td width="20%"></td><td width="20%">\it</td><td width="60%">Italic font</td><td width="20%"></td></tr>
<tr><td width="20%"></td><td width="20%">\sl</td><td width="60%">Oblique Font</td><td width="20%"></td></tr>
<tr><td width="20%"></td><td width="20%">\rm</td><td width="60%">Normal font</td><td width="20%"></td></tr>
</table>
<p>These codes may be used in conjunction with the { and } characters to limit
the change to a part of the string. For example,
</p>
<div class="example">
<pre class="example">xlabel ('{\bf H} = a {\bf V}')
</pre></div>
<p>where the character <code>'a'</code> will not appear in bold font. Note that to
avoid having Octave interpret the backslash character in the strings,
the strings themselves should be in single quotes.
</p>
<p>It is also possible to change the fontname and size within the text
</p>
<table>
<tr><td width="10%"></td><td width="40%">\fontname{<var>fontname</var>}</td><td width="60%">Specify the font to use</td><td width="10%"></td></tr>
<tr><td width="10%"></td><td width="40%">\fontsize{<var>size</var>}</td><td width="60%">Specify the size of the font to
use</td><td width="10%"></td></tr>
</table>
<p>The color of the text may also be changed inline using either a string (e.g.,
"red") or numerically with a Red-Green-Blue (RGB) specification (.e.g.,
[1 0 0], also red).
</p>
<table>
<tr><td width="10%"></td><td width="40%">\color{<var>color</var>}</td><td width="60%">Specify the color as a string</td><td width="10%"></td></tr>
<tr><td width="10%"></td><td width="40%">\color[rgb]{<var>R</var> <var>G</var> <var>B</var>}</td><td width="60%">Specify the color
numerically</td><td width="10%"></td></tr>
</table>
<p>Finally, superscripting and subscripting can be controlled with the <code>'^'</code>
and <code>'_'</code> characters. If the <code>'^'</code> or <code>'_'</code> is followed by a
{ character, then all of the block surrounded by the { } pair is
superscripted or subscripted. Without the { } pair, only the character
immediately following the <code>'^'</code> or <code>'_'</code> is changed.

<p>Conformance to both TeX and <small>MATLAB</small> with respect to the <code>\circ</code>
symbol is impossible. While TeX translates this symbol to Unicode 2218<!-- /@w -->
(U+2218), <small>MATLAB</small> maps this to Unicode 00B0<!-- /@w --> (U+00B0) instead. Octave
has chosen to follow the TeX specification, but has added the additional
symbol <code>\deg</code> which maps to the degree symbol (U+00B0).
