<h1>ol-ext: ol control profil</h1>
</a>
<div class="info">
<i>ol.control.Profil</i> is a control that draw a profil of a 3D lineString
(with a XYZ or XYZM layout).
<br/>
The control can be drawn inside or outside the map.
<br/>
It fires an <i>over</i> and <i>out</i> event with informations on the point of the profil
that is pointed by the mouse (to show the point on the map).
<ul>
<li>
<i>graduation</i> option let you specify the z axis graduation interval
</li>
<li>
<i>zmin</i> option let you specify the z axis origin
</li>
<li>
<i>zmax</i> option let you specify the z axis maximum
</li>
<li>
<i>amplitude</i> option let you specify the alitude amplitude
</li>
<li>
The <i>popup</i> function lets you show a popup when cursor fly over the profil.
</li>
</ul>
