I have a bar chart created in an asp.net web page.
The group axis (x-axis) label shows years (1990,2000,2005 etc)

My problem is that I could not change the format of that axis. It is displaying with comma seperator (1,990 2,000)
I want to get rid of the comma in the year.
I have tried File-->Options-->Fields--> Number and changed to a style that has no comma. But still, the comma is there.
Any help is much appreciated. Thanks.
