Comment(by Hello1024):
>More accurately, you could plot the "range" of pixels that would've been
plotted at that x axis position and mark the minimum and maximum.
That solves the aliasing problem.
Consider a real oscilloscope - if you have a 50Hz sine wave with aplitude
1 "added" to a 10 kHz sine wave with amplitude 0.1, and view it with a
time base suitable for the 10 Hz signal, you see the 10Hz signal with the
line "made thicker" by the higher frequency superimposed - with the above
system you would see the same.
