No background in painted rect

Richard,

To look for things in the revdocs, think of what object you are modifying.

if you know the name of the property you are looking for search the
"Reference" - that's the icon on top of the revdocs. Search graphics, you'll
find soon the right property too via the "see also". That's how I navigate
and find stuff...

If it is an object (like a graphic object), click the big object icon on top
of revdocs, select "object" in the list, then below objects is "graphic" -
look at the properties, you will find below it the "Points"... It's always
handy to read them all at some point to get aquainted with each object's
features. More power for future ideas!

Meanwhile in the jungle what you need is this:
in a button next to a graphic control you just created

get datapoint - a list of points (see revdocs for delitimiter)
set the points of graphic 1 to it

and whop (magic trick drum roll) you got a graphic with 7000 points!

This trick doesn't work for bar charts though. Pie charts, either... 

unless you try the EXCELLENT chart making stack from a fellow economist Ken
Simons at

http://www.rpi.edu/~simonk/technical.html

I think http://flexibleLearning.com has one too - H/?

and yours truly did the pie charts on monsieurx.com

Speed tips:
Separate number crunching from painting. You may not see a big difference
for smaller charts but for medium to big charts you will. 

Interpolating 7000 points on a smaller resolution graphics (say 500) will 
also get you a speed boost... A running average median function curve can do
that easily to smooth out the curve.

I'll start working on the statistics stack some time soon. I do have more
examples at http://monsieurx.com/rev in the simple examples somewhere

there it is...
