Ah. I didn't think of that. It's even better than getting every nth row, since I get one sample for a fixed period, which is what I really want. And yet better, I suppose I could do something like SELECT min(sample), max(sample) FROM mytable GROUP BY timestamp / 3600 and use financebars or similar in gnuplot to avoid missing the extremes in the plot, making it appear more or less identical as if I had plotted every value.
