title: Ploting graph of vectors using c++,linux
body: <p>I've two vectors of type double, and i want to draw their graph in the xy coordinate/axis: Now, can i have any recommendations or suggestions to do this task using c++ in Linux OS? I'm using Eigen Library to generate my vectors and to operate on matrices, any idea if Eigen have the functionality to draw graphs of vectors in real time? thanks. </p>
  
  <p>my vectors are like:</p>
  
  <pre><code>Xaxis_vector=(2,3,2,4,6,7,8,1,3) 
  Yaxis_vector=(12,13,22,4,26,7,8,21,43)
  </code></pre>
  
  <p>or a sample code as follows:</p>
  
  <pre><code>#include "Eigen/Dense"
  
  using namespace Eigen;
  using namespace std;
  
  int main()
  {
    VectorXd Xaxis_vector(10); 
    VectorXd Yaxis_vector(10); 
    for(int i=0;i&lt;10,i++)
    {
      Xaxis_vector[i]=i+1;
      Yaxis_vector[i]=2*i-4;
    }
    //In here i want to do graph plotting task...any help.
  }
  </code></pre>
