As you see,I have saved the time list as .csv,
and I want to draw Vertical Line by the script.
But it doesn't work well,it drown only one line.
I think the reason is the file pointer,although I read the programe many times,
I don't konw the further reason.
I need some help,thanks.
what follows is my script code.

Dear hexinchen,
Just remove the line FileSeek(handle,strlen,orignin); then It will work perfect. Have fun!
bro.
