				<content:encoded><![CDATA[<p>Voilà l&rsquo;autre jour je faisait un histogramme  dans un uipanel :</p>
<div class="codecolorer-container text default" style="overflow:auto;white-space:nowrap;border:1px solid #9F9F9F;width:435px;"><div class="text codecolorer" style="padding:5px;font:normal 12px/1.4em Monaco, Lucida Console, monospace;white-space:nowrap">h = uipanel;<br />
axes('parent',h)<br />
<br />
x = -4:0.1:4;<br />
y = randn(10000,1);<br />
hist(y,x)</div></div>
<p>ce qui donne </p>
<a href="http://blog.developpez.com/matlab4geek/files/2012/09/histo.png"><img src="http://blog.developpez.com/matlab4geek/files/2012/09/histo-300x224.png" alt="histogramme fait avec MATLAB" width="300" height="224" class="size-medium wp-image-186" /></a>
<p>maintenant en zoomant  :</p>
<p><a href="http://blog.developpez.com/matlab4geek/files/2012/09/histo_zoom.png"><img src="http://blog.developpez.com/matlab4geek/files/2012/09/histo_zoom-300x264.png" alt="" width="300" height="264" class="alignnone size-medium wp-image-200" /></a></p>
<p>comme on peut le voir <strong>l&rsquo;histogramme est sorti de l&rsquo;axe</strong>.</p>
<p><span id="more-182"></span><br />
<strong>La solution</strong>:</p>
<p>Elle se trouve dans le bug report : <a href="http://www.mathworks.com/support/bugreports/260354" target="_blank">Objects do not always clip to axes bounds correctly in a uipanel. </a><br />
</a></p>
<p>en rajoutant la ligne :</p>
<div class="codecolorer-container text default" style="overflow:auto;white-space:nowrap;border:1px solid #9F9F9F;width:435px;"><div class="text codecolorer" style="padding:5px;font:normal 12px/1.4em Monaco, Lucida Console, monospace;white-space:nowrap">set(gcf,'renderer','opengl')</div></div>
<p>le problème est réglé !</p>
