gnuplot

gnuplot is a graphing utility that can generate two and three-dimensional plots.

Useful for reviewing benchmarking / speedup related PRs, like #15751.

Using the data in col.csv, which was collected using bitcoind RPC calls like:

time src/bitcoin-cli deriveaddresses "wsh(multi(1,xpub661MyMwAqRbcFW31YEwpkMuc5THy2PSt5bDMsktWQcFF8syAmRUapSCGu8ED9W6oDMSgv6Zz8idoc4a6mr8BDzTJY47LJhkJ8UB7WEGuduB/1/0/*,xpub69H7F5d8KSRgmmdJg2KhpAK8SR3DjMwAdkxj3ZuxV27CprR9LgpeyGmXUbC6wb7ERfvrnKZjXoUmmDznezpbZb7ap6r1D3tgFxHmwMkQTPH/0/0/*))#t2zpj2eu" "[0,1000]"

# addresses | #15751 (s) | master (s)
100, 0.059, 0.058
500, 0.188, 0.314
1000, 0.355, 0.899
2000, 0.70, 2.953
