散点图

标准误差条形图

标准误差条形图非常适合显示置信区间。

. clear
. set obs 100
obs was 0, now 100
. gen id = _n
. expand 10
(900 observations created)
. gen u = id/30 + invnorm(uniform())
. collapse (mean) mean = u (sd) sd = u, by(id) 
. local s = invnorm(.975) * 97,5 percentile of the normal distribution
. serrbar mean sd id , scale(`s')

导出/保存图形

您可以使用图形导出命令将图形导出为 png、jpg、ps 或 pdf 格式。

. tw sc y x 
. gr export graph.png, replace

请查看 h gr export 以查看所有可用图形设备的列表。

您也可以使用图形保存命令将图形存储在 Stata 图形格式中。此格式只能由 Stata 读取。
