gnuplot

Hello,

this is not exactly a quantlib question but I thought someone here might be able to help me right away.

I have installed gnuplot 4.6.1.

now what?

how can I graph some sample points in C++?

I want to use gnuplot in my code in visual studio.

thanks

Pavan Shah

R: gnuplot

HI Pavan,

gnuplot is a standalone program. You start it (in a terminal) and run commands and it plots things. It isn’t a library that you can link to your C++ program so as to make it draw graphs directly. Technically it could be possible to reuse its code but it wasn’t designed for that and I don’t think it exposes a clean programming interface. You should make your C++ program write data points to a file, then run gnuplot and have it read them and draw the graphs.

If you want to draw graphs directly from your C++ program, you’d better use other graphics libraries. For example R has powerful graphing capabilities, it can run as a standalone program but does also expose an interface that can be called from C/C++. On the R site (www.r-project.org) you can find a lot of documentation.
