Hi, folks!
I think this question was asked many times but googling gives a rather patchy
answer to it. So, I am writing a piece of C code that acquires some data from
hardware controllers and it also has to plot a few simple graphs and
histograms
out of them. What is a "canonical" tool for such a purpose?
I played a bit with GtkExtra but it seems that the project is somewhat
forgotten
and it does not have all the documentation in it. I also looked at Cairo but
it
is a low level library so I would have to implement all the scaling, axes,
ticks
and stuff myself. There are some interactive tools based on GTK but I need a
library, as I have to build in plotting functionality.
AFAIK there's no such library, unfortunately. However gnuplot is
perhaps the nearest thing to a "canonical" open-source plotting
program. It can be run quite effectively in "slave" mode and can
produce a wide variety of output formats (notably, using cairo and
pango).
