how would you print numbers from the least significant digits to the most significant digits (like the numbers shown on the x-axis)? Thank you

Can you please clarify how this scatter plot applies to the question? — easeout, Dec 23 '09 at 05:18

Put the number in a temp.

The next digit to print is temp % 10

Divide 10 into temp.

If temp isn't 0, repeat the prior two steps.

Printing from the LSD to the MSD is actually simpler then the other way around. The reason why is that the remainder/division technique to extract the digits of a number produces the least-significant before the most-significant.

if (i == 0)
    output_digit(0)
else
    while (i != 0)
        output_digit(i % base)
        i = i / base

This will output digits in the order you want. For base 10, the number 123 will first output 3, then 2 and finally 1.
