Cytoscape 边上的箭头不显示出来
可以修改配置： Edit 菜单 | Preferences 菜单 | Properties 菜单
把600改为10000或改的更大一些。
Parameters for Controlling LOD
The default values used to determine level of detail can be changed by setting properties under Edit | Preferences | Properties….
NOTE: The greater these thresholds become, the slower performance will become. If you work with small networks (a few hundred nodes), this shouldn’t be a problem, but for large networks it will produce noticeable slowing. The various thresholds are described below.
NOTE: Since Cytoscape 3.8 interactivity will always be maintained even when a high level of detail is chosen. It is generally safe to increase the level of detail or to force full graphics details even for very large networks.
LOD Thresholds
PARAMETER | DESCRIPTION |
RENDER.COARSEDETAILTHRESHOLD | If the sum of rendered nodes and rendered edges equals to or exceeds this number, a very coarse level of detail will be chosen and all other detail parameters will be ignored. If the total number of nodes and edges is below this threshold, anti-alias will be turned on; this value defaults to 4000. |
RENDER.NODEBORDERTHRESHOLD | If the number of rendered nodes equals to or exceeds this number, node borders will not be rendered; this value defaults to 400. |
RENDER.NODELABELTHRESHOLD | If the number of rendered nodes equals to or exceeds this number, node labels will not be rendered; this value defaults to 200. |
RENDER.EDGEARROWTHRESHOLD | If the number of rendered edges equals to or exceeds this number, edge arrows will not be rendered; this value defaults to 600. |
RENDER.EDGELABELTHRESHOLD | If the number of rendered edges equals to or exceeds this number, edge labels will not be rendered; this value defaults to 200. |
When printing networks or exporting to formats such as PostScript, the highest level of detail is always chosen, regardless of what is currently being displayed on the screen.
