5 Graph Description Language (GDL) - Absint

• Arrow Heads
Enables the mode for the arrow heads to be selected.
– Inport sharing, Outport sharing (see p. 81)
– Fixed arrow heads (see arrow_mode on p. 66)
• Adding Labels (see late_edge_labels on p. 76)
• Layout Factors
Enables all the layout factors to be changed via scrollbars. For example, if the graph is too
dense, X Space and Y Space should be increased; if the splines are too sharp, the spline
factor should be reduced and the XL Space increased.
– Down factor (see layout_downfactor on p. 78 )
– Up factor (see layout_upfactor on p. 78 )
– Near factor (see layout_nearfactor on p. 78 )
– X Base (see xbase on p. 91 )
– Y Base (see ybase on p. 91 )
– X Space (see xspace on p. 92 )
– Y Space (see yspace on p. 92 )
– XL Space (see xlspace on p. 92 )
– Spline factor (see splinefactor on p. 84 )
This factor can only be changed if splines are used for edge drawing.
– Time limit
Enables a time limit for layout calculation to be set. If the time limit is exceeded, the
fastest possible mode for the current iteration phase is activated.
• Maximum Iteration Factors
Enables the maximum iteration factors for the various layout calculation phases to be
changed.
– Crossingred. (see cmax on p. 68 )
– Medium Shifts (see pmax on p. 80 )
This factor cannot be changed for the tree layout.
– Center Shifts (see rmax on p. 82 )
This factor cannot be changed for tree layout.
– Spread Level (see spreadlevel on p. 84 )
This factor can only be changed for tree layout.
– Tree Factor (see treefactor on p. 88 )
This factor can only be changed for tree layout.
– Straight Line (see smax on p. 84 )
– Bending Reduction (see bmax on p. 67 )
