I can't use formatting like this. Because, if I have a number like 29 I have to show it as 29 in the JFreeChart. If I use a format like the above, it will change the number 29 to 29.00.

If you are... A double is a value. It contains no formatting what-so-ever. So, there is no such a thing as "keep them" -- any formatting is lost when the string is converted to a double.
By default a number like 12.20 is shown as 12.2. But, I need to show it as 12.20. If the number is 12.220, I need to show 12.220. But, JFreeChart which uses decimal format drops 0 at the end.
