+/**
+ * This class is a basic plotting class using the Java AWT interface. It has basic features which allow the user 
+ * to plot multiple graphs on one figure, control axis dimensions, and specify colors.
+ * 
+ * This is by all means not an extensive plotter, but it will help visualize data very quickly and accurately. If
+ * a more robust plotting function is required, the user is encouraged to use Excel or Matlab. The purpose of this
+ * class is to be easy to use with enought automation to have nice graphs with minimal effort, but give the user
+ * control over as much as possible, so they can generate the perfect chart.
+ * 
+ * The plotter also features the ability to capture screen shots directly from the right-click menu, this allows
+ * the user to copy and paste plots into reports or other documents rather quickly.
+ * 
+ * This class holds an interface similar to that of Matlab. 
+ * 
+ * This class currently only supports scatterd line charts.
