QIPGraph is a set of C++ libraries and Excel interfaces to interact with gnuplot, a fast command line driven graphic software. Using QIPGraph, you can create complex graphics with a few simple lines of C++ or in Excel.

Here is a simple example and the matching graph output by gnuplot using C++:

#include "QIPGraph.h"

Plot plot(false,300,200); // get an instance of gnuplot

plot.command("p [-pi:pi]  cos(x)" );

You can download the 30-day free trial QIPGraph_1_0.zip file for Windows. Last build 05 March 2012. To buy it contact me.


  1. Download gnuplot. Current last version: gp444win32.zip or check at gnuplot download
  2. Extract the files in the folder C:\Program Files\gnuplot. It is important to have this folder since the Excel Add-in will look into it to get the executable.
  3. Download QIPGraph_1_0.zip and extract all files in the folder C:\Program Files\QIPGraph.
  4. Open Excel and install the add-in using Tool – Add-Ins – Browse to load the file C:\Program Files\QIPGraph\ QIPGraphGUI.xla.   
  5. C++ interface: The header files, .lib, and .dll are in the directory C:\Program Files\QIPGraph. There are no dependencies to any other library apart STL.
