In this graph I will show the moving maximum in a different color than the other values. Here are the data, A1:C14: Year Apples Above 2001 23 23 2002 45 45 2003 6 0 2004 78 78 2005 23 0 2006 54 0 2007 12 0 2008 56 0 2009 63 0 2010 72 0 2011 39 0 2012 90 90 2013 31 0 In column C2:C14 from C2 down I created the formula: =IF($B$2:$B$14>=SUBTOTAL(4;$B$2:B2);B2;0) The graph I based on both series. Series overlap: 100%. Gap width: 150%. I checked: Show data in hidden rows and columns. I hid column C.
