The interface provides methods to launch VOPlot from another java application and to manipulate VOPlot.
As of VOPlot1.3.1 the API loadVOTable(InputStream stream, boolean loadMultiple) has been replaced by two new APIs
loadVOTable(File file, boolean loadMultiple) loads VOTable from a file
loadVOTable(URL url, boolean loadMultiple) loads a VOTable from a url
