A simpler solution is to change the number format.
This won't work if you have no idea a priori what the max will be, but
if you know it's 10,000, double click the axis, click on the Number tab,
select Custom in the left side, and type this in the entry box:
[=10000]$#,##0;#,##0
If you know it's going to be at least 10,000, but aren't sure exactly
what, use this:
[>=10000]$#,##0;#,##0
