<P> Each data point in a polar plot is represented by a tuple consisting
|
|
|
30 |
of a radius and an angle. The polar plot itself can be either outlined
|
|
|
31 |
or filled. In addition each point may have a standard marker (the same
|
|
|
32 |
as for line and scatter plots).</P>
|
|
|
33 |
<P> The scale for the radius can be either linear or logarithmic.</P>
|
|
|
34 |
<P> A polar graph is created by creating an instance of <A href="../ref/PolarGraph.html#_POLARGRAPH_POLARGRAPH">
|
|
|
35 |
PolarGraph::PolarGraph()</A>. The polar graph type inherits all the
|
|
|
36 |
capabilities of ordinary X-Y graphs, i.e they can have background
|
|
|
37 |
images, background gradients, tabbed titles and so on.</P>
|
|
|
38 |
<P> Polar graphs comes in two basic types, they can either show a full
|
|
|
39 |
360 degree graph or a half 180 degree graph. The two examples below
|
|
|
40 |
show these two basic types of graphs.</P>
