如何不截断图形 hbox 类别名称

Question

我好像遇到过不少这个问题，但一直没有找到满意的解决方案。

当使用水平箱线图 (graph hbox) 时，类别上的变量标签会​​被截断并挤压在图表和图像边界之间，如附件所示。

这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。

可在here 找到重现此图的完整数据集。

任何想法将不胜感激。

Answer 1

造成这种情况的原因是20、30 等之后的'，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
""                      . 1
""                      . 1
"."                    56 1
"."                     . 1
"20 or less"          47 1
"20 or less"         132 1
"30 or less" 39.09157895 1
"30 or less"           . 1

"50 or less"           . 1
"75 or less" 32.82857143 1
"75 or less"           . 1
"75 or more"         102 1
"75 or more"         107 1
"None"        30.96176471 1
"None"                  . 1
"Random"               60 1
"Random"                . 1
end

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

Answer 2

我可以用这个数据子集复制问题：

* Example generated by -dataex-. To install: ssc install dataex
clear
input str11 q40 double yield byte tag
""                      . 1
""                      . 1
"."                    56 1
"."                     . 1
"20' or less"          47 1
"20' or less"         132 1
"30' or less" 39.09157895 1
"30' or less"           . 1
"50' or less" 50.09548059 1
"50' or less"           . 1
"75' or less" 32.82857143 1
"75' or less"           . 1
"75' or more"         102 1
"75' or more"         107 1
"None"        30.96176471 1
"None"                  . 1
"Random"               60 1
"Random"                . 1
end

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

并且可以通过这种修补获得看起来合理的标签。

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

箱形图自然不严重。我只关注报告的问题。

我不明白为什么这么长（或这么短）的文本标签会有问题。直觉只是轴长明显太长，所以应该缩短。

该解决方案也适用于完整数据集。
