没有人知道吗？急啊！！

你先上传一个样本数据，别人才好画

你是想画出每个年龄组中男女所占的频率/比例吗？为什么不画histogram？

同意楼上的建议，画直方图就挺好的了

actually, there is a solution.

or




At a guess you want
egen freq = total(1), by(dr1995 mat blind)

egen tag = tag(dr1995 mat blind)

scatter dr1995 mat if blind == 1 & tag [fw=freq] || ////

scatter dr1995 mat if blind == 2 & tag [fw=freq] ||
