Hi ,
i need to show a graph whihc has months as category axis and value as y axis. i need to show values of last 12 months and also against each monh what was the value 12 months ago... eg. if i have data as on NOV 2014 - 134 and NOV 2013 - 100. then i need to show in one graph bar showing 134 and lie shwoing 100 etc.... i tried using a formula... like if month = nov 2014 then make it nov 2013 .. etc but when i filter the graph for last 12 months... since nov 2013 is excluded im unable to see 12 months back value... if i want it then am ending up with blanks at starting
