<p>JpGraph library is an OO graph library which makes it easy to both draw a "quick and
dirty" graph with a minimum of code and quite complex graphs which requires a very fine
grain of control. The library tries to assign sensible default values for most parameters
hence making the learning curve quite flat since for most of the time very few commands are
required to draw graphs with a pleasing esthetic look.</p>
<p>The following list makes no claim to be complete but it will give a birds view of some of
the main (and in some cases unique) features of the library. The list will also illustrate
the difference between the free and the pro-version.</p>

<p>In addition to these high level features the library has been designed to be orthogonal
and consistent in its' naming convention. For example, to specify color each object (i.e.
axis, grids, texts, titles etc) within the graph implements the method
<code class="code">SetColor()</code> with the same signature. </p>
