                  else if (row == 4) printf(" -2\n");
                  else printf("\n");
              }
              // Print the x-axis markers
              printf("%s\n", x_axis);
              // Print the x-axis labels
              printf("-16 -14 -12 -10 -8  -6  -4  -2  0   2   4   6   8\n");
              printf("\n");
          }
