电泳EPLAY串口传输的图形数据表示是4位表示一个Y座标。把空格去掉，按Y座标画折线图就行。（知道4位一个Y就简单了直接是十进制额）
数据示例（按4个字符处理一个Y座标）

//s datastr=testStr
//s data=""
s ystr=""
f i=1:4:($l(datastr)-20) d
.s curNum=$REPLACE($e(datastr,i,i+3)," ","")
.//s data=data_$lb(+curNum)
.i $l(ystr) s ystr=ystr_"^"_(curNum)
.e s ystr=ystr_(curNum)
然后按标准画折线图就OK了
