Producing Plots

[daviddoria]

Is there a package for c++ that will allow me to make a matlab/gnuplot style plot from within c++? I would like to skip the step of writing data to a file and then using something else to read in the data and then plot it. I tried koolplot, but I occasionally have to code in windows and I couldn't get it to work (they only provide a .a library which windows doesn't like).

Thanks!
