Stata的图形依赖于类和对象,而这些类和对象没有文档。
使用classutil
命令可以看到以下内容:
sysuse auto, clear
twoway scatter mpg price
classutil describe .Graph.plotregion1
plotregion .Graph.plotregion1:
classwide:
dbstyle .dbstyle
instancespecific:
plotregionstyle .style
(output omitted)
double .drawn_gmult = 1
double .drawn_yalpha = -2225.574929548387
double .drawn_ybeta = 589.5383153548387
double .drawn_xalpha = 3669.808224
double .drawn_xbeta = 1.697641630579655
double .drawn_gbeta = 232.72
string .dialog = "plotregion"
(output omitted)
这些也可以根据需要进行操作:
display `.Graph.plotregion1.drawn_yalpha'
-2225.5749
display "`.Graph.plotregion1.dialog'"
plotregion
对话框是否有类似内容?
例如,我想提取对话框的尺寸或位置。
