caling gnuplot from c++

[nagendradh]

Dear All.
I am writing a program in C++ that writes the data in a file. I can plot it. But I want to call gnuplot from the program when it is running so that I can see the update of the data. How is this done in C++. May you help me please?

I presume you would format your file in a way that gnuplot and read then execute gnuplot using a system() call. When gnuplot completes, control is returned to your program.

I've not actually done this but I'm guessing this is what you have to do.
