Barand You are the Best! I know sometimes I run in to an end and the solution is there but just hard to find after staring at the same code for days, you my friend are a great start to my weekend! Best to you. And just so you know I posted this on Stack Overflow and was told that I did not try enough and i should try harder before asking questions. I will speak highly of this form and stick around to see if I can help others as well.1 point

try foreach ($array as $k => $d) { if ($k > 0) { if (strtotime($d) > strtotime($array[$k-1])+6) { $new[] = "-------------------"; } } $new[] = $d; } $new = Array ( [0] => 2021-02-10 09:04:48 [1] => 2021-02-10 09:04:54 [2] => 2021-02-10 09:05:00 [3] => 2021-02-10 09:05:06 [4] => 2021-02-10 09:05:12 [5] => 2021-02-10 09:05:18 [6] => ------------------- [7] => 2021-02-10 09:06:18 [8] => 2021-02-10 09:06:24 ) [edit...] Alternative solution... $new = []; $newkey = 0; foreach ($array as $k => $d) { if ($k > 0) { if (strtotime($d) > strtotime($array[$k-1])+6) { $newkey++; } } $new[$newkey][] = $d; } gives $new = Array ( [0] => Array ( [0] => 2021-02-10 09:04:48 [1] => 2021-02-10 09:04:54 [2] => 2021-02-10 09:05:00 [3] => 2021-02-10 09:05:06 [4] => 2021-02-10 09:05:12 [5] => 2021-02-10 09:05:18 ) [1] => Array ( [0] => 2021-02-10 09:06:18 [1] => 2021-02-10 09:06:24 ) )1 point

Define customer/product as UNIQUE...

TIP: If you are creating home-grown charts, plotting the values is the easy bit. 95% of the coding effort will be in the drawing of chart area, plot area, axes, axis labels, scaling, titles etc. You can sidestep this with a simple table with horizontal bars. EG CODE EXAMPLE... <?php $values = [ 'Strongly Disagree' => 7, 'Disagree' => 10, 'Neither' => 12, 'Agree' => 25, 'Strongly Agree' => 41 ]; function valueChart(&$values) { $out = "<table class='chartTable'> <tr><th>Response</th> <th>Total</th> <th>Percent</th> </tr> "; $totalVal = array_sum($values); foreach ($values as $resp => $n) { $out .= "<tr><td>$resp</td> <td class='ra'>$n</td> <td>" . bar($n / $totalVal * 100) . "</td></tr>\n"; } $out .= "</table\n"; return $out; } function bar($val=0) { $a = '#3399ff'; $b = '#e6f2ff'; $c = '#0066cc'; $bg = '#eee'; $width = 300; $height = 25; $svg = <<<SVG <svg width='$width' height='$height' viewBox='0 0 $width $height'>"; <defs> <linearGradient id="bargrad" x1="0" y1="0" x2="0" y2="1"> <stop offset="0%" style="stop-color:$a"/> <stop offset="25%" style="stop-color:$b"/> <stop offset="100%" style="stop-color:$c"/> </linearGradient> </defs> <rect x='0' y='0' width='$width' height='$height' style='fill:$bg' stroke='#999'/> SVG; $w = $val/100 * $width; $svg .= "<rect x='0' y='0' width='$w' height='$height' style='fill:url(#bargrad)' />"; $svg .= "</svg>\n"; return $svg; } ?> <!DOCTYPE html> <html lang="en"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Chart Example</title> <head> <style type='text/css'> .chartTable { font-family: arial, sans-serif; font-size: 11pt; } th { padding: 4px 16px ; } td { padding: 0 16px; } .ra { text-align: right; } </style> </head> <body> <?=valueChart($values)?> </body> </html> Hope this helps.
