comparison artifacts/src/main/java/org/dive4elements/river/utils/DataUtil.java @ 7081:3c4efd4b2c19 generator-refactoring
Simplyfy / unify "invert axis" logic
- DataUtil now can check if two datasets are in the same direction
- In the case of WKM data a no means that the Water flows Right to Left
- If the water flows from right to left do inversion of diagrams
