    Plotting in C++?

    In matlab it very easy to plot a function:

    x = [1:10]
    y = x.*20
    plot(x,y)

    A little windows pops up with the graph and some editing options. Is there
    anything like this for C++, or do I have to write a rasterizer from scratch?

      There are libraries available you can use if you do not want to write
      your own, perhaps you can even uses Matlab in some way.

          Which?

          I would like to avoid any dependency on matlab

              C++ doesn't specify such a library as part of the standard. Depending on
              what you're trying to accomplish, you can use native plotting
              capabilities under most systems (e.g. SetPixelV under Windows) or you
              can use a semi-portable library for a pretty fair number of systems
              (e.g. Qt, wxWidgets). Most of these more or less require a fair amount
              of nonstandard code though...

                  One can always plot in two colors as follows using only the
                  standard library. (Even without the large gaps visible here)
                  Or you can write to a file and use an external plotter, such as gnuplot.

                      Would OpenGL do what you want?

                          I personally suggest you could use "dislin", it is a package that fit
                          your need. It can used in C++ to plot graphs. see
