Ich verwende Highcharts-Kreisdiagramme in meiner Anwendung, bei der die Daten für das Kreisdiagramm aus der Datenbank übernommen werden. Meine Frage ist nach dem Ausfüllen von Kreisdiagrammen, wenn ich auf einen bestimmten Bereich klicke, sollte er auf einer bestimmten PHP-Seite dargestellt werden. Ist es möglich?

Hier ist mein Code:

    function open_risk_level_pie()
    {
    $chart = new Highchart();

    $chart->chart->renderTo = "open_risk_level_pie";
    $chart->chart->plotBackgroundColor = null;
    $chart->chart->plotBorderWidth = null;
    $chart->chart->plotShadow = false;
    $chart->title->text = "Risk Level";

    $chart->tooltip->formatter = new HighchartJsExpr("function() {
    return '<b>'+ this.point.name +'</b>: '+ this.point.y; }");

    $chart->plotOptions->pie->allowPointSelect = 1;
    $chart->plotOptions->pie->cursor = "pointer";
    $chart->plotOptions->pie->dataLabels->enabled = false;
    $chart->plotOptions->pie->showInLegend = 1;
    $chart->plotOptions->pie->colors = array('red', 'orange', 'yellow', 'black');
    $chart->credits->enabled = false;

    // Open the database connection
    $db = db_open();

// Get the risk levels
$stmt = $db->prepare("SELECT * from `risk_levels`");
$stmt->execute();
$array = $stmt->fetchAll();
$high = $array[0][0];
$medium = $array[1][0];
$low = $array[2][0];

    // Query the database
    $stmt = $db->prepare("select a.calculated_risk, COUNT(*) AS num, CASE WHEN a.calculated_risk >= " . $high . " THEN 'High' WHEN a.calculated_risk < " . $high . " AND a.calculated_risk >= " . $medium . " THEN 'Medium' WHEN a.calculated_risk < " . $medium . " AND a.calculated_risk >= " . $low . " THEN 'Low' WHEN a.calculated_risk < " . $low . " AND a.calculated_risk >= 0 THEN 'Insignificant' END AS level from `risk_scoring` a JOIN `risks` b ON a.id = b.id WHERE b.status != \"Closed\" GROUP BY level ORDER BY a.calculated_risk DESC");
    $stmt->execute();

    // Store the list in the array
    $array = $stmt->fetchAll();

    // Close the database connection
    db_close($db);

    // If the array is empty
    if (empty($array))
    {
            $data[] = array("No Data Available", 0);
    }
    // Otherwise
    else
    {
            // Create the data array
            foreach ($array as $row)
            {
                    $data[] = array($row['level'], (int)$row['num']);
            }

            $chart->series[] = array('type' => "pie",
                    'name' => "Level",
                    'data' => $data);
    }

echo "<div id=\"open_risk_level_pie\"></div>\n";
echo "<script type=\"text/javascript\">";
echo $chart->render("open_risk_level_pie");
echo "</script>\n";

}
