interfacing with gnuplot without pipes

[Alexander Stippler]

Hello,

I want to visualize numerical results with gnuplot. The easiest way would be
to
use a pipe to gnuplot. But I want to be platform independent, just relying
on
the C++-standard. What is the recommended way of getting this functionality?

regards,
alex

There is none.

You have an option of writing your gnuplot commands into a file
and then use 'system' function to run gnuplot, but the contents
of the string you pass to 'system' has got to be system-specific.
So, no truly system-independent way.

The C++ Standard does not mention GNUplot. This is obviously just an
oversight - expect ISO to fix it soon.

But until then, rely on this recent post: "I found gnuplot is really nice.
There are some c/c++ interfaces, through which gunplot command could be sent
from c/c++ program. --phony"

Since advising phony to use GNUplot, I also advised him to switch to Python
and use BLT (under PythonMegaWidge ts). These systems are (almost) as
portable as C++, but they don't have C++'s issues with exposed plumbing. And
BLT provides interactive hooks so you can supply drill-down, pans, zooms,
etc.

Again: Why are you using C++?

I used Google

http://www.google.com/

to search for

+"gnuplot interface" +"C++"

and I found lots of stuff. This one

http://ndevilla.free.fr/gnuplot/

just happened to appear at the top of the list.

The above links look good, however, its worth noting that the C++
library (as well as other language libraries which use gnuplot, all
depend on the presence of POSIX threads in the underlying OS.
