我知道如何更改顶点的大小,但是当我这样做时,TreeLayout会将节点放置成边缘消失,即。节点重叠,边缘不可见。如果我更改布局(到KKLayout),边缘会自动变大,图形看起来很干净。我想知道是否可以将节点分开/增加TreeLayout本身边缘的长度? (保持树层次结构的任何其他建议也很棒)
答案 0 :(得分:1)
您可以在构建TreeLayout
时定义节点之间的空间。这会增加边长:
TreeLayout treeLayout = new TreeLayout<String, Integer>(graph, 500, 500);
如果您没有为distx
或disty
输入值,则默认为50.构造函数:
/**
* Creates an instance for the specified graph, X distance, and Y distance.
*/
public TreeLayout(Forest<V,E> g, int distx, int disty) {
if (g == null)
throw new IllegalArgumentException("Graph must be non-null");
if (distx < 1 || disty < 1)
throw new IllegalArgumentException("X and Y distances must each be positive");
this.graph = g;
this.distX = distx;
this.distY = disty;
buildTree();
}
