good tip! now i understood what i did wrong. i always used the same
functionType - still (time -> currency) where i should have used (index ->
(time, currency)).
but can you tell me if there is an easier way to get the data displayed as
points than constructing everything new?
i already have a datareference that can be displayed (time -> currency).
especially regarding the same problem for the 3d display, i get a bit
worried because i don't think i understood how to construct a point plot.
what would it have to look like???
