I would like to plot a line with two-color dashes, say red-blue-red-blue-...
I know I could do it like this:
plot([1,2],[1,2],'r'),

I've been looking through some of the tools available for measuring network throughput, namely iperf, bwping, ttcp, etc. I am planning on doing throughput tests over a long period of time, so what I really need is good graphing output, preferably rrd graphs.
The Jperf frontend for iperf will generate…
