Scott,
That will help alot. It leads me to another question. A little background:
I'm trying to create a voting app that shows the probability of a number of
outcomes happening historically. I can pull that data as {datetime,score}
for each possible outcome and then normalize it in JS with the other scores
at that datetime so the probability of all the outcomes = 1 (or 100% -
however you want to say it). This would require me to generate the file
whenever somebody requests it after somebody voted on that outcome.
Or, I can pull the data pre-normalized, but then it would be best to pull
the data like {outcome_id,datetime,normalized_score} which doesn't seem to
be something that timeplot can handle AFAIK. This would be the functional
equivalent as the above situation but it's N-1 fewer queries where N is the
number of outcomes.
The third option is to simply generate a file for each possible outcome and
update it every time somebody requests the data after somebody else voted on
ANY outcome.
Have you or anybody else dealt with this kind of situation?
Thanks very much,
Adam
