Creating 2 dimentional graphs

[DarkoX]

Hey, i've wrote a script that will test three diffrent sorting methods and display how much time each method took to complete in order to compare the diffrent methods. The problem is that i'm suppose to show the results inside a 2 dimentional graph, and i'm not that much of an expert in c++ and zero knowledge in c++ graphics, so i was wondering if someone could help me out, i'm using visual studio 2008.

here's what i have:

#include<ctime>
#include <cstdlib> 
  using std::rand;                                                      
  using std::srand;
#include<iostream>
 using namespace std;
 
void BubbleSort (int *q , int n)
{
     int permut , i , aux;
     do
     {
         permut = 0;
         for(i=0 ; i<n-1; i++)
            if(q[i]>q[i+1])
            {
                aux = q[i];
                q[i] = q[i+1];
                q[i+1] = aux;
                permut = 1;
            }   
      }while(permut==1);      
}

void SelectionSort (int *q , int n)
{
     int i , j , aux , imin;
     for(i=0 ; i<n-1 ; i++)
        {
            imin = i ;
            for(j=i+1 ; j<n ;j++)
               if(q[j] < q[imin])
                  imin = j;
            if(imin!=i)
            {
                aux = q[imin];
                q[imin] = q[i];
                q[i] = aux;
            }
        }
}     

void InsertionSort (int*q , int n)
{
     int i , j , k , newVal;
     for(i=0 ; i<n ; i++)
     {
         newVal = rand();
         j=0;
         while((j < i) && (q[j] <= newVal))
            j++;
         for(k=i-1 ; k>=j ; k--)
            q[k+1] = q[k];
         q[j]=newVal;
     }
}

What i'm looking for is somekind of a plugin or a script that will display these results inside a graph(in a pop up window maybe?!!)

Good luck on finding a plug in or script. There are three options I can think of. 1) You can search the net and try to find something. 2) You can hang around here (or some other site) until someone gives you a reference. 3) You can work something up yourself. C++ doesn't come with native support for graphics, though there are graphics programs written in C++. Learning to use them has a learning curve so don't expect to become an expert overnight. If your project isn't due for another week or two and you don't have anything else to do but this, then you can probably do it. If you want referals for one of the graphics programs post the request (or search the board/site) and you will probably get several suggesstions. The alternative is to write a program using ASCII characters, which you already have all the necessary skills to do. All it takes is a nested loop to display the relative values obtained from av1, av2, and av3. That should allow you to do something like this:

av1 | *************
av2 | *****
av3 | *********

where each * represents 0.1 seconds, or whatever. It may not be the most sophiscticated 2 dimensional graph, but it is something you can do without learning anything new.
