+
+	In CrossSection Diagram fix subtitle to display the km of which the data is
+	actually displayed (maybe contrasting users wish).
+
+	* src/main/java/de/intevation/flys/artifacts/WINFOArtifact.java:
+	  (getCrossSectionSnapKm): New method to fetch the actual km of crosssection.
+
+	* src/main/java/de/intevation/flys/exports/CrossSectionGenerator.java:
+	  Add correct km to charts subtitle.

 	Fix various display-issues like i18n in cross-section diagram.
