Post subject:  Combo Chart is not working

Hi,
i'm using pChart2.1.3 and have to draw a combo charts. I tried this example code from the website:

Code:
/* pChart library inclusions */
include("/usr/local/lib/pChart/class/pData.class.php");
include("/usr/local/lib/pChart/class/pDraw.class.php");
include("/usr/local/lib/pChart/class/pImage.class.php");

/* Create the pData object with some random values*/
$MyData = new pData();
$MyData->addPoints(array(30,24,32),"This year");
$MyData->addPoints(array(28,20,27),"Last year");
$MyData->addPoints(array("Year","Month","Day"),"Labels");
$MyData->setAbscissa("Labels");

/* Create the pChart object */
$myPicture = new pImage(700,230,$MyData);

/* Create a solid background */
$Settings = array("R"=>179, "G"=>217, "B"=>91, "Dash"=>1, "DashR"=>199, "DashG"=>237, "DashB"=>111);
$myPicture->drawFilledRectangle(0,0,700,230,$Settings);

/* Do a gradient overlay */
$Settings = array("StartR"=>194, "StartG"=>231, "StartB"=>44, "EndR"=>43, "EndG"=>107, "EndB"=>58, "Alpha"=>50);
$myPicture->drawGradientArea(0,0,700,230,DIRECTION_VERTICAL,$Settings);
$myPicture->drawGradientArea(0,0,700,20,DIRECTION_VERTICAL,array("StartR"=>0,"StartG"=>0,"StartB"=>0,"EndR"=>50,"EndG"=>50,"EndB"=>50,"Alpha"=>100));

/* Add a border to the picture */
$myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));

/* Write the picture title */
$myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/Silkscreen.ttf","FontSize"=>6));
$myPicture->drawText(10,13,"Chart title",array("R"=>255,"G"=>255,"B"=>255));

/* Draw the scale */
$myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->setGraphArea(50,60,670,190);
$myPicture->drawFilledRectangle(50,60,670,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10));
$myPicture->drawScale(array("CycleBackground"=>TRUE));

/* Graph title */
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
$myPicture->drawText(50,52,"Chart subtitle",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMLEFT));

/* Draw the bar chart chart */
$myPicture->setFontProperties(array("FontName"=>"/usr/local/lib/pChart/fonts/pf_arma_five.ttf","FontSize"=>6));
$MyData->setSerieDrawable("Last year",FALSE);
$myPicture->drawBarChart();

/* Draw the line and plot chart */
$MyData->setSerieDrawable("Last year",TRUE);
$MyData->setSerieDrawable("This year",FALSE);
$myPicture->drawSplineChart();
$myPicture->drawPlotChart();

/* Make sure all series are drawable before writing the scale */
$MyData->setSerieDrawable("This year",TRUE);

/* Write the legend */
$myPicture->drawLegend(540,35,array("Style"=>LEGEND_ROUND,"Alpha"=>20,"Mode"=>LEGEND_HORIZONTAL));

/* Render the picture (choose the best way) */
$myPicture->render("diagramm.png");

echo "<img src=\"diagramm.png\">";


And as an result i got this chart:

As you can see i get two splines and two bars and not only one! I played a little around to find the bug and so i find out that the

$MyData->setSerieDrawable(....)

is not working - it's just ignored. Can anybody help me???

Thanks a lot
Milly

Having the same problem. setSerieDrawable() is not working for me also.
However my series are independent, so I use removeSerie() instead :shock:

Any ETA on any work on this problem? It works on the examples online, but not on the download.
