Line jumps represent an intersection of lines. If you have a large diagram with lots of intersecting paths, line jumps make the diagram easier to understand. The line jumps are not displayed by default.

   • None - specifies that the diagram use no line jumps (default value).
     
   • Horizontal Line - specifies that line jumps appear only on horizontal line.
     
   • Vertical Line - specifies that line jumps appear only on vertical line.
