Changing data source of graph

I'm really green when it comes to excel syntax and programming in VBA but I have previously made graphs for March through June. Now I need to change the source of the graph to be from November through March. I've tried looping down my dates to find the cell with November 1st and March 31st, insert the row from those dates and the column of that data into the formating code I got from the macro recorder and loop through the graphs to format them all in one fail swoop but to no avail.

Any suggestions?
