NOTE: I have read the "set decimalsign lcale" in the manual - which seems the usual advice.
However, that deals with changing the the usual English decimal point, not adding a thousands separator.
I would like to display my ytics as "2,000,000"
How can I achieve this?
gnuplot uses the standard C-style formatting for its tic labels, so there isn't really a good way to do this automatically. If you know where you want the tics you can specify them manually, e.g.:
set ytics ("0" 0, "1,000,000" 1e6, "2,000,000" 2e6)
You can type ? set xtics for more info.
If you want to do it automatically, there may be a way to write a gnuplot function implementing something like the solution here, but that may be more trouble than it is worth.
