Best way to display data from c code ?

[JoKKeR]

Atm. im working on solar heating project and i need many things calculated and visualized. Also on the way im learning c programming.


I need X Y type plot like thing.

So iv written a code to output variables to .TXT file and then im using MS office (excel) to visualize . TXT file seems ok but i cant build chart in some weird way. All seems right but i cant see line between axes.


Are there other ways to display data straight from program ?

#include<stdio.h>
#include <math.h>

int main()
{
    int a = 0;
    double b = 1;
    double c = 1;
    
    FILE *f;
    f = fopen("test.txt","w");
      
    while (a < 1000){
    a++;
    
    b = b * 1.01;
     
    fprintf(f,"%2.3f             %d              1 \n",b, a);
}

  system("PAUSE");	
  return 0;
}

Hi,

I think that the best way is to write a GUI program, that can not just calculate, but also to draw your data.
