 for ($i=0;$i<=360;$i=$i+10) { $myData->addPoints(cos(deg2rad($i))*20,"Probe 1"); }
 for ($i=0;$i<=360;$i=$i+10) { $myData->addPoints(sin(deg2rad($i))*20,"Probe 2"); }

 /* Create the Y axis and the binded series */
 for ($i=0;$i<=360;$i=$i+10) { $myData->addPoints($i,"Probe 3"); }
 $myData->setSerieOnAxis("Probe 3",1);
