使用的命令是：
quietly psmatch2 dum_e0 $x $ch2 $z2 ,outcome(y) n(1) ate ties logit common
pstest $x $ch2 $z2 ,both graph

psgraph


出现报错

. psgraph //
no; data are mi set
    Use mi reshape to perform reshape on these data.  mi reshape has the same syntax as reshape.

    Perhaps you did not type reshape.  In that case, the command you typed calls reshape and it is not appropriate for use with mi
    data.  Use mi extract or mi xeq to select the data on which you want to run the command, which is probably m=0.


用的chfs（中国家庭金融数据库）的数据，想得到下面这个图，但是却报错，不知道怎么调整，求助一下大家
