Re: [Gretl-users] First time to plot a series after installation of gretl
I tried wgnuplot, found it loaded and plotted instantly. Rebooted and
found no difference.
I tried GRETL again, tested for graphing from console vs right-click on
a series. I thought I perceived a faster time from the console -- but
if there was, it was marginal.
I noticed this graph delay in my class last spring, but after the first
few sessions the students ignored it. All the machines in the lab are
older PCs, low memory.

Thanks for the info. This narrows the issue down. One more
question: how does the start-up time for gretl itself compare
depending on whether it's the first invocation since booting
Windows, versus closing gretl and restarting it? Is that
difference less extreme than for a gnuplot graph?
Oh, and another experiment people could try, if they have the
patience: what about the start-up time for wgnuplot.exe (the
executable is in the gretl installation directory), independent of
gretl? I'm thinking that the time to place a gretl/gnuplot graph
on the screen is not all "gnuplot time": gnuplot is called to
generate a PNG file, which gretl then displays using GTK/GDK, and
the load time for the relevant GTK modules may be a factor.
