Create Dynamic graph

I have a sheet of data (see enclosed).

I have created dynamic graphs before but this graph is a little different. In my other graphs that i have done the dynamic variable is the x-axis.......like if i were adding a new month. But in this one I am adding a new month but the month is not the x-variable (see enclosed file). As such i am not sure how to make this graph dynamic.

In this graph the x-variables are static........

Any ideas?
