Question

When you are trying to represent the behavior of some quantity that varies over time, one of the usual tools is the line graph, in which a set of data values are plotted on an x-y grid with each pair of adjacent points connected by a straight-line. For example, given the following set of 10 points: (0.0, 0.67) (0.4, 0.68) (0.8,0.71) (1.2,0.86) (1.6,0.86) (2.0,1.30) (2.8,1.81) (3.2,1.46) (3.6,1.86)

Write a function DrawLineGraph that generates a line graph given an array of x-coordinate values, a second array of corresponding y-coordinate values, and the number of data points.

Explanation / Answer

#include <iostream>
#include "koolplot.h"

using namespace std;

int main()
{
   int x[20], y[20], n
   cout << "Enter the number of data points to be used"
   cin >> n;
   cout << "Enter x values";
   for(int i=0, i<n, i++)
   {
       cin >> x[i];
   }
   cout << "Enter y values";
   for(int i=0, i<n, i++)
   {
       cin >> y[i];
   }

for(int i = 0, i<n, i++)
{
   addMarx(x[i], y[i], xCoord, yCoord);
}
plot(x, y);
return 0;
}
