One really simple idea: group points by their x pixel, connecting the max and min y values for each with a vertical line.

feel free to experiment, but i suspect that any workable solution is not going to be cheap enough and is likely to not be simple and high quality.
you must be able to simplify each data series as a stream (during the path drawing loop itself) rather than allocating another set of 3 x 50,000-element pixel offset arrays, which will eat up all the benefit very quickly.
im on a phone, but will look into it later, thanks!
if you want to open an issue in the repo to work on porting this to the lib for actual apples-to-apples comparison, that would be cool, too :)
I added code for gaps. The tight loop isn't disrupted that much; the number of interruptions is bounded by the x resolution.
