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