ah the getChartLayoutInterface() function is what i needed, i kept looking for it but couldn't find it
and just to make sure is my approach of calling the DRAW function every time new data comes in is correct for real time updates, right? there is no way to just update the chart you just have to redraw the whole thing to update it seems like. also, i have noticed that the plot takes up a lot of RAM as the number of samples grow and i have to use averaging to reduce the number of samples displayed to preserve memory. this is also a problem for me because i want to be able to display data over a long time but i am limited by the plot's ram usage. now on Safari it all works fine without taking up much memory but on chrome it grows very fast! i know that chrom uses a seperate process per tab but i am not sure how to make it work like safari so that i can display a huge sample without memory burden.
