why not just change your array structure a little so that the date is the
key, and the elements are the values. so it would look like this.
Array
(
[Jan-99] => Array
(
[0] => 6399.36
[1] => 6132.71
[2] => 2242.20
[3] => 53.27
[4] => 87.34
)
[Feb-99] => Array
(
[0] => 5754.72
[1] => 3964.93
[2] => 6145.98
[3] => 693.32
[4] => 23.80
)
)
That would make it much easier. I think.
