1.1 数据集

1.2 代码

proc sgplot data = sashelp.cars;vbar origin / response = msrp  /* response：响应变量，Y轴 */stat = mean   /* stat：统计量，结果用均值呈现 */group = type  /* group：组别 */groupdisplay = cluster  /* groupdisplay：组别显示，cluster离散，stack堆叠（默认） */limitstat=stddev  /* limitstat：误差线，CLM置信限，STDDEV标准差，STDERR标准误 */limits=upper; /* limits：误差线显示，upper仅显示上，lower仅显示下，both上下都显示（指定limitstat下默认） */xaxis label = "原产地";  /*修改横坐标轴*/yaxis label = "MSRP($)"; /*修改纵坐标轴*/keylegend / location = inside position = topright down = 3 title = "Type" noborder ; /*图例设置*/title color = red height = 2 "添加标题名称" ;  /*修改标题，参数放在标题前，否则不执行*/footnote "添加脚注";  /*修改脚注*/
run;
