电泳EPLAY串口传输的图形数据表示是4位表示一个Y坐标。把空格去掉，按Y坐标画折线图就行。（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坐标）

/s testStr=" 2 0 0 1 3 4 6 7 8 9 12 14 17 19 24 32 43 57 73 93 124 168 228 311 417 550 708 0 914 724 556 412 297 209 146 102 73 57 49 51 57 66 80 98 124 158 199 250 315 398 509 654 49 992 775 599 456 347 264 205 165 137 116 103 97 98 107 120 137 157 182 215 259 319 400 510 652  805 600 432 303 210 148 108 84 69 62 60 63 66 69 68 64 60 60 68 86 115 158 214 287 378 488 617 764 0 937 766 609 473 362 276 213 168 137 120 113 113 116 125 138 157 177 202 232 269 314 371 444 539 661 0 982 722 516 361 250 176 129 101 84 71 62 52 45 38 35 32 31 30 30 30 31 32 35 37 38 37 35 31 28 24 21 20 21 23 5 0 53 97 140 179 233" //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
