Thanks for for the suggestion but this didn't seem to work. I beleive
it is a header conflict based on what I have researched.
I just can't seem to find a solution.

The code in the PHP block:
echo "TEST DATA PRINT";
print_r($datay,false);
is passing all the values from the sql query because I can see them on
the page with the jpgraph error.
For example:
TEST DATA PRINTArray ( [0] => 665 [1] => 7093 [2] => 3 [3] =>
45816 [4] => 70848 [5] => 41365 [6] => 35676 [7] => 22434 [8] => 5450
[9] => 29131 [10] => 35244 [11] => 48614 [12] => 51748 [13] => 55497
[14] => 79042 [15] => 732 [16] => 1375 [17] => 1094 [18] => 897 [19]
=> 1122 [20] => 3059 [21] => 5350 [22] => 5080 [23] => 3082 [24] =>
2737 [25] => 326 [26] => 1334 [27] => 736 [28] => 469 [29] => 127 [30]
=> 105 [31] => 111 [32] => 197 [33] => 208 [34] => 950 [35] => 9 [36]
=> 9 [37] => 19 [38] => 8 [39] => 17 [40] => 90 [41] => 1917 [42] =>
1289 [43] => 2051 [44] => 1534 [45] => 1 [46] => 2 [47] => 4 [48] => 4
[49] => 7 [50] => 8 [51] => 9 [52] => 18 [53] => 22 [54] => 5 [55] =>
3 [56] => 1 [57] => 1 [58] => 2 )
JpGraph ERROR 25121

but I am unable to get my arrays from the sql query to populate the graph.
Thank you in advance,

[PHP-DB] Re: jpgraph and mysql passing array
Would you try an experiment?
In this line:
$sql = ("SELECT * FROM evdobanding WHERE Market like '%$term' and Cell_Sect =
'$term2' and Date = '$term3' ORDER BY distance asc");
Change to:
$sql = "SELECT * FROM evdobanding WHERE Market like '%".$term."' and Cell_Sect
= '".$term2."' and Date = '".$term3."' ORDER BY distance asc";
That is, remove the parenthesis and concatenate the variables into the string.

If $datay shows as empty, my first step would be to check that your SQL
query doesn't return an empty set.
