+	* src/main/java/de/intevation/flys/exports/ChartGenerator.java: Modified
+	  and renamend getDomainAxisRange(). This method is now called
+	  getDomainAxisRangeFromRequest() and returns no longer a Range object but
+	  a String array that consists of the raw string values specified in the
+	  request document.
+
+	* src/main/java/de/intevation/flys/exports/XYChartGenerator.java:
+	  Implemented the missing method getDomainAxisRange(). This method returns
+	  a Range object based on the String array returned from
+	  getDomainAxisRangeFromRequest().
