So even if you try to plot 5000 points on a 500 pixel area you only
need to plot 500 of the data points that actually fall on distinct
integer coordinates
It makes things go faster
That is a good idea. If a data point falls on the exact same pixel
as the
previous one (horizontally AND vertically) then there is not need
to draw
it.
Exactly
I'm definitely putting that one on my list
