<h2>2.3: Colorbars and legends&nbsp;<a href="User_guide2.html"><img src="Images/uparrow.png" border="0" align="top" alt="Go back up one level"/></a></h2>
<p>(The code for this example can be found here:
[ <a href="Examples/colorbarexample.m">view</a>
| <a href="matlab: edit(fullfile(layoutDocRoot,'Examples','colorbarexample.m'))">edit</a>
| <a href="matlab: p=pwd();cd(fullfile(layoutDocRoot,'Examples')); colorbarexample; cd(p)">run</a> ]
)</p>
<p>
When using layouts to position axes that can also have a
colorbar or legend it is very important to group the axes
with its colorbar and legend by putting them inside a <code>uicontainer</code>.
</p>
<p>
The following example illustrates this.
</p>
<h4>Open a window</h4>
<p>Open a new figure window and remove the toolbar and menus.</p>
<example><pre style="background-color: #eeeeff; margin-left: 20px; margin-right: 20px"><font color="#000011">window = <a href="matlab:doc figure"><code class="FUNCTION">figure</code></a>( 'Name', 'Axes legend and colorbars', ...
'MenuBar', 'none', ...
'Toolbar', 'none', ...
'NumberTitle', 'off' );</font></pre>
</example>
<h4>Create the layout</h4>
<p>The layout involves two axes side by side. Each axes is placed into a uicontainer so that the legend and colorbar are "grouped" with the axes.</p>
<example><pre style="background-color: #eeeeff; margin-left: 20px; margin-right: 20px"><font color="#000011">hbox = <a href="uix.HBoxFlex.html"><code class="FUNCTION">uix.HBoxFlex</code></a>('Parent', window, 'Spacing', 3);
axes1 = <a href="matlab:doc axes"><code class="FUNCTION">axes</code></a>( 'Parent', <a href="matlab:doc uicontainer"><code class="FUNCTION">uicontainer</code></a>('Parent', hbox) );
axes2 = <a href="matlab:doc axes"><code class="FUNCTION">axes</code></a>( 'Parent', <a href="matlab:doc uicontainer"><code class="FUNCTION">uicontainer</code></a>('Parent', hbox) );</font></pre>
<p style="background-color: #ddddee; margin-left: 20px; margin-right: 20px"><font color="#000022"><center><img src="Images/colorbar_example_2.png"/></center></font></p>
</example>
<h4>Add decorations</h4>
<p>Give the first axes a colorbar and the second axes a legend.</p>
<example><pre style="background-color: #eeeeff; margin-left: 20px; margin-right: 20px"><font color="#000011"><a href="matlab:doc surf"><code class="FUNCTION">surf</code></a>( axes1, <a href="matlab:doc membrane"><code class="FUNCTION">membrane</code></a>( 1, 15 ) );
<a href="matlab:doc colorbar"><code class="FUNCTION">colorbar</code></a>( axes1 );
<br/>
theta = 0:360;
<a href="matlab:doc plot"><code class="FUNCTION">plot</code></a>( axes2, theta, <a href="matlab:doc sind"><code class="FUNCTION">sind</code></a>(theta), theta, <a href="matlab:doc cosd"><code class="FUNCTION">cosd</code></a>(theta) );
<a href="matlab:doc legend"><code class="FUNCTION">legend</code></a>( axes2, 'sin', 'cos', 'Location', 'NorthWestOutside' );</font></pre>
<p style="background-color: #ddddee; margin-left: 20px; margin-right: 20px"><font color="#000022"><center><img src="Images/colorbar_example_3.png"/></center></font></p>
