Improve OperatorGraphVisualizationView

Reported by: mkommend Owned by: mkommend
Priority: low Milestone: HeuristicLab 4.x Backlog
Component: Operators.Views.OperatorGraphVisualization Version: 3.3
Keywords: Cc:


This ticket collects all review comments for the OperatorGraphVisualization.

  • The boxes grow in size when the text gets larger, but they do not shrink again when the text gets smaller.
  • Sometimes the arrow is not drawn when connecting two operators, or it's drawn wrong.
  • The red square surrounding a port still remains selected sometimes after creating a connection.
  • In the operator graph view it's possible to add operators to the selection by (ctrl|shift)-clicking, but not removing them again through another (ctrl|shift)-click.
  • Placing two operators in the operator graph view above each other and left-clicking selects the operator on top, but right-clicking opens the context menu on the bottom one.
  • I'd like an option to increase/decrease the font size and increase/decrease the arrow strength in the operator graph view.
  • The flow chart is very nice, but sometimes arrows are a bit wild and going backwards which creates a not so nice strikethrough appearance. Would be good to have non-direct arrows as well.
  • The OperatorGraphVisualization doesn't respect operator collections (e.g. SequentialSubScopesProcessor).
  • Top-down layouting would be better instead of left-right for two reasons:
    1. The boxes are usually much wider than high and thus a left-right layout makes the graph even longer.
    2. A top-down graph better fits the paper orientation in a publication.
  • Icon for expanding/collapsing details is rather confusing (undo/redo), should be +/- .
  • A zoom rectangle tool would be nice.
  • Panning while pressing the middle mouse button would be nice too.
  • Display updates while scrolling and panning are rather slow.
  • After zooming out in the operator graph visualization multiple times (approx. 50 times) an exception is thrown.

Replying to gkronber:

@architects: Reject?

In my opinion, yes reject. Operator graphs and their graphical representation are not in the strategic focus of HL development anymore. Furthermore, the priority is also "low".
