I am creating a simulation of atmospheric CFC concentration from 1980 to 2100 and plotting using a plotting panel with trail. The x-axis is stuck with a scientific notation format 1.980 x10^3   ..... 2.100 x10^3.  I'd like it to be 1980. ... 2100.  I can't seem to figure out how to change this.  
Any help will be greatly appreciated.
