stata twoway bar 怎么去掉柱体和x轴之间的空白

需要用twoway bar 画图（不用graph bar），画出的图柱体与X轴总是有一段空白，如何去掉空白，让柱体从X开始向上呢？

1. sysuse sp500, clear
   
2. gen month=month(date)
   
3. collapse  high low volume close, by(month)
   
4. gen month1=month-0.2
   
5. gen month2=month+0.2
   
6. 
   
7. twoway  (bar high month1,barw(0.4)) (scatter volume month,msymbol(S) connect(l) yaxis(2))   ///
   
8. (bar low month2, barw(0.4)), xlabel(1(1)12)

复制代码

希望达到的效果：

1. sysuse sp500, clear
   
2. gen month=month(date)
   
3. collapse high low volume close,by(month)
   
4. gen month1=month-0.2
   
5. gen month2=month+0.2
   
6. twoway (bar high month1,barw(0.4)) (scatter volume month,msymbol(S) connect(l) yaxis(2)) (bar low month2, barw(0.4)), xlabel(1(1)12) plotregion(margin(tiny))
