Right before the line where you call to_polygons(), add this line: multipolygon.should_simplify = False The simplification logic gets triggered automatically if the rcParam['path.simplify'] is True and if there are more them 128 vertices and those vertices are all simple LINETO segments. I think in your situation, this is true. So, we can force a non-simplification directly like above, or set your rcParams file with path.simplify to False (but this may make graph rendering significantly slower and more resource intensive overall). The path simplification logic is designed so that one does not see any visual differences, however, there might need to be some additional logic for those who are accessing the path directly. I hope this helps! Ben Root
