"Fatal error: Unsupported operand types in C:\xampp\htdocs\bitacora\jg\jpgraph_pie3d.php on line 444" obviamente la libreria no esta mal, yo estoy pasando el dato mal o no se :(

Código HTML:
<?php

$query = mysql_query("select b_act,count(b_act) from bitacora GROUP by b_act");
$result = mysql_num_rows($query);
for ($punt=0;$punt<$result;$punt++)
{
$resultd = mysql_fetch_array($query);
$arreglo1[]=$resultd['b_act'];
$arreglo2[]=$resultd['count(b_act)'];
}
$graph = new PieGraph(450,200,"auto");
$graph->img->SetAntiAliasing();
$graph->SetMarginColor('gray');
$graph->SetShadow();
// Setup margin and titles
$graph->title->Set("Ejemplo: Horas de Trabajo");
$p1 = new PiePlot3D($arreglo1);
$p1->SetSize(0.35);
$p1->SetCenter(0.5);
// Setup slice labels and move them into the plot
