From source file:org.n52.oxf.render.sos.ScatterPlotChartRenderer.java

/**
 * The resulting IVisualization shows a scatterplot.
 * /*from w w  w  . j a  v a 2  s .c  o  m*/
 * Auf X- und Y-Achse wird jeweils eine observedProperty abgetragen.
 * 
 * Ein Punkt steht dann fr ein Wertepaar (X,Y) fr ein FOI zu einem bestimmten Zeitpunkt.
 * 
 * TODO PROBLEM: Macht nur Sinn, wenn fr jedes (FOI, Time)-Tuple jeweils ein Wert fr BEIDE
 * observedPropertys enthalten ist !!!!
