+	* src/main/java/de/intevation/flys/artifacts/charts/CrossSectionApp.java:
+	  Use separate XYDataset for each curve. This is needed because 
+	  "Raum/Flaeche" needs specialized renderers, which are not compatible
+	  with the standard renderers.
+
+	* src/main/java/de/intevation/flys/artifacts/CollectionMonitor.java:
+	  Removed superfluous import.
