 funct         


        

Answer 1

i solve this problem using role style technique now for charts that generate dynamic data i used a random function to generate color

    function random_color_part() {
return str_pad( dechex( mt_rand( 0, 255 ) ), 2, '0', STR_PAD_LEFT);
}

function random_color() {
return random_color_part() . random_color_part() . random_color_part();
}
then simply
$color=random_color();
print "['$rows[1]',$rows[2],'#$color'],\n";
