/**
 * <P>This component implements the chart interface and allows data obtained via the use of ChartHandles to be plotted onto a graph.</P>
 * <P>The VisADOutputSynapse uses the visad display library, more details on this can be obtained from http://www.visad.org.</P>
 * <P>When the property show is set to true a JFrame is displayed, this will display a chart of any previously obtained data or no chart if
 * the data has not yet been obtained.  When the network starts the component collects the data in internal buffers and at the end of the
 * network run will display the data in a chart.  Serie lines are coloured according to the choice made in the specific ChartHandle object.</P>
 * <P>The displayed component allows the user to change the X and Y range of data that should be displayed, this allows ther user to zoom in ans out of the data range.</P>
 * <P>The user can also decided whether to display the data as points and whatthe point size can be.</P>
 * <P> Multi serie plots can be done by the use of ChartHandles.  Mono plots can be done by connecting this to a normal Layer.</P>
 *<P> This component will throw an network error if it runs out of memory, the network will then stop running.</P>
