    Can I make a plot?

    Let's say I've got the following function. It outputs an array that represents a sine wave for two periods. Is there a way I can ouput it to my screen so that it makes graph? I've used GNUplot but I was wondering if there was a way I could do it dirrectly in C++. Could this also be done in C?
    Code:
    #include <iostream>
    #include <math.h>
    
    using namespace std;
    
    int main()
    {
    double y[200];
    int i;
    
    for (i=0; i<200; i++)
    y[i]=sin(2*M_PI*(i)/100);
     
    for (i=0; i<200; i++)
    cout<< y[i]<<endl;
    
    return 0;
    }

    There are no C or C++ standard functions that will do that. You have to use operating-specific functions or a cross-platform library such as wxWindows, QT, or the GNU drawing package you already use.
