android object/ class structure for graphing
<p>Am currently developing an android application that requires real time data viewing with achartengine: still in the application design:</p>

<p>My data will be presented in two types:</p>

<ol>
<li>plain data</li>
<li>charts - using achartengine
      in this category i will have several graph types like line chart, bar, pie e.t.c</li>
</ol>

<p>The problem that am having when designing class diagrams for the application is that am stuck on whether to handle Graphs as a package then have the graph types as a class inside the package or create a class for each graph type which resides on my application package..</p>

<p>Kindly help me out on this.</p>
