title: How to plot Histogram and Dot diagrams and save to picture in C++
body: <p>I have tested a lot of different C++ library's(SIGL, PLplot, libharu and some other randoms) for plotting but i have not found anyone that suites my need or is working properly.</p>
  
  <p>My need is to create a histogram and a dot diagram using 100 000 - 1000 000 values from a 2 dimensional matrix. Save it to a picture png or jpeg format preferred. 
  I use Visual studio 2010 and have a Windows XP operating system.
  I need to be able to use C++ and I would prefer if there was some good documentation on the library too.</p>
  
  <p>Note is that I do not want to use Matlab, since that is what I am replacing.</p>
  
  <p>Love
