00032 // A single data series abstracted.
00033 // Is included in a DataSeriesBag.
00034 // Will be a base class for other series objects, such as DataVectorSeries,
00035 // and DataQuerySeries.
00036 //
00037 // Requirements:
00038 // - Able to handle its own parameters, colours, legend texts, etc.
00039 // - Able to hide/show itself.
00040 // - Almost completely abstract, so we can inherit it from other classes.
00041 //   Implement things like hide and show here tho.
