[Physltest] [Phys-L] Re: loggerpro question on video analysis

[Cindy Schwarz <schwarz@VASSAR.EDU>]

i had problems too - i tried it again - I had your problem at first and
I had to go into something and set something and then it worked (sorry
cant remember exactly what) but then after I did the clicking I could
not get a graph - help said something about a plot window or strip and
I couldnt ever find that - in the end I decided if it took that long
for me to figure out and I couldn't get it to work it was not worth it


so we will try tilting the camera and use LoggerPro - but please John
G. if you have any pull tell them to get the rotate axes in
