Thanks
not really a bluetooth question but .. plot less points. The screen is about 1000px wide on a high def phone, so if you're plotting a time series there's not a lot of point plotting more than 1000 points and really a couple of hundred would most likely do just fine to show a graph of that sort of data. Plot every 100th point and you are now down to .35 seconds. If someone zooms in, plot the same number of points taken from the smaller interval. |
