Oh, I didn't really take notice of the original code, sorry. I don't need that extra flag there - just use $last_topic for both purposes :

Code:

<?php
  
    $last_topic = NULL;

    echo "<categories>\n";
    foreach($bfg_charts_midnightmysteries as $row)
        echo "<category label='" . $row->Days . "'/>\n";

    echo "</categories>\n";
    
    foreach($bfg_charts as $row)  {
        // If parent matches the previous parent, don't show it - just indent a bit
        if ($row->Title == $last_topic)
            echo "";
        else  {
            if ($last_topic)
                echo "</dataset>\n";
            echo "<dataset seriesName='" . $row->Title . "'/>\n";
            }
        // You're always showing the child information
        echo "<set unusedLabelDate='" . $row->Date . " unusedLabelDays='" . $row->Days . "' value=" . $row->Rank . "/>\n";
        
        // Set last topic to current topic (for test on next loop)
        $last_topic = $row->Title;
        }
    echo "</dataset>\n";
?&gt;

That should work the same way - untested code, of course.
