comparison artifacts/src/main/java/org/dive4elements/river/exports/DiagramGenerator.java @ 7076:7f600001c807 generator-refactoring
Add LTR inversion code to diagram generator.
This code is used in serveral diagrams and as it modifies a
whole diagram it should be central. (This should also make
maintenance easier). This function can be called by processors
to make sure that their data is plotted with an LTR waterflow.
