\caption{LOTUS tree: Intermediate and terminal nodes are represented by
circles and squares, respectively. The number inside a node is the
node label and the splitting rule of an intermediate node is given
beside it. If a case satisfies the rule, it goes to the left child node;
otherwise the right child node. The ratio of cases with Y=1 to the
node sample size is given beneath each terminal node.}

我更改了以下行中的某些参数：
psset{tnsep=2pt,tnheight=0cm,treesep=.01cm,levelsep=1pt,radius=50pt}
但仍然看不到整个图表。请帮忙，谢谢
