<P> Each data point in a polar plot is represented by a tuple consisting
 of a radius and an angle. The polar plot itself can be either outlined
 or filled. In addition each point may have a standard marker (the same
 as for line and scatter plots).</P>
<P> The scale for the radius can be either linear or logarithmic.</P>
<P> A polar graph is created by creating an instance of <A href="../ref/PolarGraph.html#_POLARGRAPH_POLARGRAPH">
PolarGraph::PolarGraph()</A>. The polar graph type inherits all the
 capabilities of ordinary X-Y graphs, i.e they can have background
 images, background gradients, tabbed titles and so on.</P>
<P> Polar graphs comes in two basic types, they can either show a full
 360 degree graph or a half 180 degree graph. The two examples below
 show these two basic types of graphs.</P>
