<p>Contour group objects are created by the <code>contour</code>, <code>contourf</code>, and
<code>contour3</code> functions.  The are also one of the handles returned by the
<code>surfc</code> and <code>meshc</code> functions.  The properties of the contour group
are
</p>
<dl compact="compact">
<dt><code>contourmatrix</code></dt>
<dd><p>A read only property that contains the data return by <code>contourc</code> used to
create the contours of the plot.
</p>
</dd>
<dt><code>fill</code></dt>
<dd><p>A radio property that can have the values <code>&quot;on&quot;</code> or <code>&quot;off&quot;</code> that
flags whether the contours to plot are to be filled.
</p>
</dd>
<dt><code>zlevelmode</code></dt>
<dt><code>zlevel</code></dt>
<dd><p>The radio property <code>zlevelmode</code> can have the values <code>&quot;none&quot;</code>,
<code>&quot;auto&quot;</code>, or <code>&quot;manual&quot;</code>.  When its value is <code>&quot;none&quot;</code> there is
no z component to the plotted contours.  When its value is <code>&quot;auto&quot;</code> the z
value of the plotted contours is at the same value as the contour itself.  If
the value is <code>&quot;manual&quot;</code>, then the z value at which to plot the contour is
determined by the <code>zlevel</code> property.
</p>
</dd>
<dt><code>levellistmode</code></dt>
<dt><code>levellist</code></dt>
<dt><code>levelstepmode</code></dt>
<dt><code>levelstep</code></dt>
<dd><p>If <code>levellistmode</code> is <code>&quot;manual&quot;</code>, then the levels at which to plot
the contours is determined by <code>levellist</code>.  If <code>levellistmode</code> is set
to <code>&quot;auto&quot;</code>, then the distance between contours is determined by
<code>levelstep</code>.  If both <code>levellistmode</code> and <code>levelstepmode</code> are
set to <code>&quot;auto&quot;</code>, then there are assumed to be 10 equal spaced contours.
</p>
</dd>
<dt><code>textlistmode</code></dt>
<dt><code>textlist</code></dt>
<dt><code>textstepmode</code></dt>
<dt><code>textstep</code></dt>
<dd><p>If <code>textlistmode</code> is <code>&quot;manual&quot;</code>, then the labeled contours
is determined by <code>textlist</code>.  If <code>textlistmode</code> is set to
<code>&quot;auto&quot;</code>, then the distance between labeled contours is determined by
<code>textstep</code>.  If both <code>textlistmode</code> and <code>textstepmode</code>
are set to <code>&quot;auto&quot;</code>, then there are assumed to be 10 equal spaced
labeled contours.
</p>
</dd>
<dt><code>showtext</code></dt>
<dd><p>Flag whether the contour labels are shown or not.
</p>
</dd>
<dt><code>labelspacing</code></dt>
<dd><p>The distance between labels on a single contour in points.
</p>
</dd>
<dt><code>linewidth</code></dt>
<dt><code>linestyle</code></dt>
<dt><code>linecolor</code></dt>
<dd><p>The properties of the contour lines.  The properties <code>linewidth</code> and
<code>linestyle</code> are similar to the corresponding properties for lines.  The
property <code>linecolor</code> is a color property (see <a href="Colors.html#Colors">Colors</a>), that can also
have the values of <code>&quot;none&quot;</code> or <code>&quot;auto&quot;</code>.  If <code>linecolor</code> is
<code>&quot;none&quot;</code>, then no contour line is drawn.  If <code>linecolor</code> is
<code>&quot;auto&quot;</code> then the line color is determined by the colormap.
</p>
</dd>
<dt><code>xdata</code></dt>
<dt><code>ydata</code></dt>
<dt><code>zdata</code></dt>
<dd><p>The original x, y, and z data of the contour lines.
</p>
</dd>
<dt><code>xdatasource</code></dt>
<dt><code>ydatasource</code></dt>
<dt><code>zdatasource</code></dt>
<dd><p>Data source variables.
