x axis on chart can't be adjusted correctly

Hi,
I have attached a worksheet that is showing sales in 2009 and 2010. One problem I am having is that chemicals #1 and #2 were only used in 2010. However, if I try to change the x-axis to 2010 for these two then it changes it for all chemicals. I essentially want #1 and #2 to be showed on the 2010 side of the graph on not on the 2009 side. Thanks.!
