Dataflow is reversed

Question

Newbie question: My dataflow appears to be reversed. I am attempting to layout the flow between tables in a data warehouse. Arrows point backwards, from successor  to predecessor rather than predecessor to successor. The whole chart is rendered upside-down, with the end of the flow at the top. I'm using the Orthagonal > Classic layout. How can I fix this? A colleague (who is on vacation for a week) used yEd to create the original dataflow diagram and the arrows point correctly on his old version.

Answer 1

Orthogonal layout has no idea about the direction of a flow. Use Hierarchical layout instead. Your links can still have orthogonal shape with this algorithm.

Comments

It turns out my colleague tweaked the .gml file to reverse the arrows by swapping the predecessors & successors! Cool that you can do that; it's pretty simple to do using a text editor.

You do not even need a text editor to do that. In yEd, select the edges you want to reverse, then use "Tool" -> "Reverse Selected Edges".
Alternatively, you can switch the source and target arrow of selected edges in the properties view in yEd's lower right corner.

That's slick. Thank you!
