Creating a rolling year.

[spheriad]

I have created a bar chart with flash, and using PHP to supply the data. My problem is my boss wants the information in a rolling year, starting with the current month and working out. For example, the graph would start in april and end in march. Right now I have the graph from Jan. to Dec. using an 2 dimensional array. One dimensional for the data and one for the month. What I can't figure out is how to start from the current month and end in the previous month. Any help with this would be a great help.

 

thanks,

date("n") is the month number of the current month.  If you plot 12 data points that'll end in the 'previous' month.

 

Maybe I misunderstood the question.

I have figured out this problem. Here is how I did it:

 

for ( $i = 0; $i < 12; $i += 1){
$monthArr[$i][1] = date("M",strtotime("+$i month"));
for ($j = 0; $j <12; $j += 1){
	if ($arrData[$j][1] == $monthArr[$i][1]){
		$newMonth[$i][1] = $monthArr[$i][1];
		$newMonth[$i][2] = $arrData[$j][2];
	}
}
}
