Maybe I'm missing something obvious, but I can't seem to find a way to plot the moving average of a pen - is this possible ~~without scripting the calculation~~? (it seems I can't even do it via scripting since the Power Chart doesn't accept anything but tag source data 😕 )  
Note: this is possible in Vision

I'd also like to know more about how to implement moving average in perspective.
