I'm not aware of any explicit upper bound for data points. But since the data points are stored in an STL array internally, it is subject to the upper bounds of the platform (typically the max value of either size_t or signed 32-bit integer). In practice, it is far larger than 3200, and probably so large that you would never hit that theoretical maximum value. Having said that, the current chart implementation is very susceptible to poor performance when passing a large data set, in practice you wouldn't want to pass too many data points, else Calc's run time performance would suffer. How many data points would be considered too many is pretty much dependent on your PC.
