Please let me summarize in my own words:

If you display 4000 rates on a 400-pixel wide graph, you want to
see 10 dots per column, not a line or an area connecting an
minimum, average, maximum or last.

Correct?

If so:

This would require programming (in rrd_graph.c and friends).

In my example of 10 dots per column, how do you suggest RRDtool graph
should show these rates: 1 1 1 3 4 7 7 7 7 ?

Should it show 6 dots of equal size,
should it show 2 large dots and two small dots,
or ... ?


If my summary is not correct, then what do you mean?
