Php Html - How can I draw a graph of an array

0 votes

I discovered an array's mean, mode, median, and standard deviation. Now I'd like to plot them in a graph. I want to create an array line chart and highlight the mean, mode, median, and standard deviation. I tried something below, but only the x and y axes appeared, with no digits; I'm new to php. I need assistance converting my array to a line chart. Is there anyone who can assist me? Thank you very much.

My code is:

<?php   
echo "Welcome to my project".'<br>'.'<br>'; 
$arr=array(1100,3150,4430,4430,5170,7450,7450,7450,8230);
for($i=0; $i<=8; $i++)
{
    if ($arr[$i]<100) {
    $arr[$i]=$arr[$i];
 }
    else
    {
        $arr[$i]=$arr[$i]/1000;
        $arr[$i]=(string)$arr[$i];
    }
}

function calculate($arr, $output){

        switch($output){
            case 'mean':
                $count = count($arr)+1;
                $sum = array_sum($arr);
                $total = $sum / $count;
            break;
            case 'median':
                rsort($arr);
                $middle = (count($arr) / 2)+1;
                $total = $arr[$middle-1];
            break;
            case 'mode':
                $v = array_count_values($arr); 
                arsort($v); 
                foreach($v as $k => $v){$total = $k; break;}

            break;

        }
        return $total;
    }

function sd_square($x, $total) { return pow($x - $total,2); }
function sd($arr) {
    return sqrt(array_sum(array_map("sd_square", $arr, array_fill(0,count($arr), (array_sum($arr) / count($arr)) ) ) ) / (count($arr)-1) );
}

echo '  '.'<br>';
echo "Values: ";
echo json_encode($arr).'<br>';
echo 'Mean: '.calculate($arr, 'mean').'<br>';
echo 'Median: '.calculate($arr, 'median').'<br>';
echo 'Mode: '.calculate($arr, 'mode').'<br>';
echo "Standart Derivation: ".sd($arr);
?>
