Post Combo ScatterPlot and ScatterLine
I am having trouble creating a combo chart with a scatterplot of all my data and a scatterline of the averages. I can create a scatterplot of both data sets and a scatterline of both data sets but I can't seems to set one data set on each chart in the same image.

Below is my code (php):
Code:
    $DataSet = new pData();
        $DataSet->addPoints($weekNum,"WeekData");       
        $DataSet->addPoints($yield,"YieldData");

        $DataSet->addPoints($Avgyield,"AvgYieldData");       
        $DataSet->addPoints($AvgweekNum,"AvgWeekData");

// create scatter plot   
/* Create the X axis and the binded series */
$DataSet->setAxisName(0,"Week");
$DataSet->setAxisXY(0,AXIS_X);
$DataSet->setAxisPosition(0,AXIS_POSITION_BOTTOM);

/* Create the Y axis and the binded series */
$DataSet->setSerieOnAxis("YieldData",1);
$DataSet->setAxisName(1,"Yield");
$DataSet->setAxisUnit(1,"%");
$DataSet->setAxisXY(1,AXIS_Y);
$DataSet->setAxisPosition(1,AXIS_POSITION_LEFT);

/* Create Avg Data */ 
$DataSet->setSerieOnAxis("AvgYieldData",1);
$DataSet->setScatterSerie("AvgWeekData","AvgYieldData",2);
$DataSet->setScatterSerieDescription(2,"Weekly Avg");
$DataSet->setScatterSerieShape(2,SERIE_SHAPE_SQUARE);
$DataSet->setScatterSerieColor(2,array("R"=>255,"G"=>0,"B"=>0));


/* Create the 1st scatter chart binding */
$DataSet->setScatterSerie("WeekData","YieldData",0);
$DataSet->setScatterSerieDescription(0,"Lot Avg");
$DataSet->setScatterSerieColor(0,array("R"=>0,"G"=>0,"B"=>0));

/* Create the pChart object */
$myPicture = new pImage(400,400,$DataSet);

/* Draw the background */
$Settings = array("R"=>170, "G"=>183, "B"=>87, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);
$myPicture->drawFilledRectangle(0,0,400,400,$Settings);

/* Overlay with a gradient */
$Settings = array("StartR"=>219, "StartG"=>231, "StartB"=>139, "EndR"=>1, "EndG"=>138, "EndB"=>68, "Alpha"=>50);
$myPicture->drawGradientArea(0,0,400,400,DIRECTION_VERTICAL,$Settings);
$myPicture->drawGradientArea(0,0,400,20,DIRECTION_VERTICAL,array("StartR"=>0,"StartG"=>0,"StartB"=>0,"EndR"=>50,"EndG"=>50,"EndB"=>50,"Alpha"=>80));

/* Write the picture title */
$myPicture->setFontProperties(array("FontName"=>"Fonts/tahoma.ttf","FontSize"=>10));
$myPicture->drawText(10,16,"Title",array("R"=>255,"G"=>255,"B"=>255));

/* Add a border to the picture */
$myPicture->drawRectangle(0,0,399,399,array("R"=>0,"G"=>0,"B"=>0));

/* Set the default font */
$myPicture->setFontProperties(array("FontName"=>"Fonts/pf_arma_five.ttf","FontSize"=>10));

/* Set the graph area */
$myPicture->setGraphArea(50,50,350,350);

/* Create the Scatter chart object */
$DataSet->setSerieDrawable("AvgYieldData", FALSE);
$DataSet->setSerieDrawable("AvgWeekData", FALSE);
$myScatter = new pScatter($myPicture,$DataSet);

/* Draw the scale */
$myScatter->drawScatterScale();

/* Draw a scatter plot chart */
$myScatter->drawScatterPlotChart();

/* Draw the legend */
$myScatter->drawScatterLegend(225,390,array("Mode"=>LEGEND_HORIZONTAL,"Style"=>LEGEND_NOBORDER));

/* Draw the picture  */
$myPicture->Stroke();
