• stretch Type: integer Default value: 1 Attribute of: top-level graph, subgraphs Description: See graph attribute shrink (p. 83). • subgraph_labels Type: yes, no Default value: yes Attribute of: top-level graph Description: no: Switches off the displaying of subgraph labels. This can also be done interactively from the View dialog box. • tempfactor Type: float Default value: 1.3 Attribute of: top-level graph Description: This attribute only applies to the forcedir layout algorithm. It is used in the simulated annealing part of the algorithm. It specifies the temperature scheme factor used for exponential and reverse exponential temperature schemes. For details, see p. 115. • tempmin Type: integer Default value: 1 Attribute of: top-level graph Description: This attribute only applies to the forcedir layout algorithm. Here it is used in the simulated annealing part of the algorithm. It specifies the lower limit of the temperature range. For details, see p. 115. • tempmax Type: integer Default value: 128 Attribute of: top-level graph Description: This attribute only applies to the forcedir layout algorithm. Here it is used in the simulated annealing part of the algorithm. It specifies the upper limit of the temperature range. For details, see p. 115. 86
• tempscheme Type: integer Default value: 1 Attribute of: top-level graph Description: This attribute only applies to the forcedir layout algorithm. There are local and global temperature schemes. In global temperature schemes all nodes have the same temperature. – 1 (local temperature temp_speed) Local adaptive temperature scheme with speedup during cooling. – 2 (local temperature temp_normal) Local adaptive temperature scheme with no speedup. – 3 (global temperature temp_linear) Linear curve. – 4 (global temperature temp_hyperbolical) Hyperbolic curve: very fast descent, then a low temperature for an extended period of time – 5 (global temperature temp_exponential) Exponential descending temperature, i. e. a small temperature for an extended period of time. – 6 (global temperature temp_logarithmic) Logarithmic descending, i. e. a small temperature for an extended period of time. – 7 (global temperature temp_reverse_exponential) Reverse exponential descending temperature, i. e. a high temperature for an extended period of time. – 8 (global temperature temp_reverse_logarithmic) Reverse logarithmic descent, i. e. a high temperature for an extended period of time. For details, see p. 115. • temptreshold Type: integer Default value: 3 Attribute of: top-level graph Description: This attribute only applies to the forcedir layout algorithm. Here it is used in the simulated annealing part of the algorithm. It specifies the threshold value for the global temperature. The algorithm stops if the global temperature drops below the value specified here. For details, see p. 115. • textcolor Type: black, blue, red, ... 87
