Graph 如何不截断图形hbox类别名称

我似乎经常遇到这个问题，但没有找到令人满意的解决办法

使用水平框和胡须图（

graph hbox

）时，类别上的变量标签会被截断，并在图形和图像边界之间压缩，如所附的图所示

以下是我生成图表的代码：

graph hbox yield, over(q40) 

我需要12个空格来呈现类别名称，但在Stata或Stata手册中找不到如何设置标签长度

可以找到复制此图的完整数据集

任何想法都将不胜感激

我可以用这个数据子集复制问题：

* Example generated by -dataex-. To install: ssc install dataex

input str11 q40 double yield byte tag
""                      . 1

"None"                  . 1
"Random"               60 1
"Random"                . 1
end

set scheme s1color 
graph hbox yield, over(q40) name(G1) 

通过这种修补可以得到外观合理的标签

graph hbox yield, over(q40) aspect(1) name(G2) 

当然，方框图并不严重。我只关注报道的问题

我不知道为什么这么长（或这么短）的文本标签会有问题。直觉是轴的长度显然太长了，所以应该缩短

该解决方案也适用于完整的数据集

导致这种情况的原因是

之后的
，
30等，可能与Stata如何在内部解析字符串变量
q40
有关。使用与@NickCox相同的数据子集：

clear

input str11 q40 double yield byte tag

end

graph hbox yield, over(q40) name(G1, replace) 

斑点清晰，但仍然神秘@NickCox我认为Stata会被内部解析的双引号和单引号的数量弄糊涂。事实上，我“几乎证明”我的情况就是这样。困惑是疾病，而不是原因。显然，Stata应该为本地宏引用查找左开引号和右闭引号，但它们不在这里，我们正在丢失大部分标签。我不知道发生了什么事。
