Hi,
I 30,000 paired data points (x,y) that are generated by my program. I need to create an overview display like here: http://finance.google.com/finance?q=NASDAQ:CSCO where the bottom graph shows the all the data.
What method of analysis/averaging is best to us to show the user an overview of the data? I thought about avergaing every 20 points or so, but I'm afraid to lose big spikes followed by small spikes. Any ideas?
