Php 为什么pchart图表不呈现？我已经安装了gd2

我正在尝试将图表集成到网站中。我通过查看示例测试了gd2安装，这些示例是有效的。然后我继续将其集成到我的php文件中，使用以下代码：

 include("grafice/class/pData.class.php");
 include("grafice/class/pDraw.class.php");
 include("grafice/class/pImage.class.php");

  //creaza si populeaza obiectul
 $MyData = new pData();  
 $MyData->addPoints(array(4,VOID,VOID,10,8,3),"Proba 1");
 $MyData->addPoints(array(3,10,5,8,5,5),"Proba 2");
 $MyData->addPoints(array(2,7,5,1,9,2),"Proba 3");
 $MyData->setSerieTicks("Proba 2",4);
 $MyData->setSerieWeight("Proba 3",2);
 $MyData->setAxisName(0,"Note");
 $MyData->addPoints(array("Ian","Feb","Mar","Apr","Mai","Iun"),"Labels");
 $MyData->setSerieDescription("Labels","Luni");
 $MyData->setAbscissa("Labels");

 // creaza obiectul chart
 $myPicture = new pImage(700,230,$MyData);


 //deseneaza fundalul
 $Settings = array("R"=>170, "G"=>183, "B"=>87, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);
 $myPicture->drawFilledRectangle(0,0,700,230,$Settings);

 // suprapune un gradient
 $Settings = array("StartR"=>219, "StartG"=>231, "StartB"=>139, "EndR"=>1, "EndG"=>138, "EndB"=>68, "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"=>80));

 // bordura
 $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));

 // titlul pozei
 $myPicture->setFontProperties(array("FontName"=>"fonts/Silkscreen.ttf","FontSize"=>6));
 $myPicture->drawText(10,13,"EXEMPLU",array("R"=>255,"G"=>255,"B"=>255));

 // titlul graficului 
 $myPicture->setFontProperties(array("FontName"=>"fonts/Forgotte.ttf","FontSize"=>11));
 $myPicture->drawText(250,55,"Media Notelor",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));

 //deseneaza marimea 1 
 $myPicture->setGraphArea(60,60,450,190);
 $myPicture->drawFilledRectangle(60,60,450,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10));

 $AxisBoundaries = array(0=>array("Min"=>0,"Max"=>10));
 $scaleSettings  = array("GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE,"Mode"=>SCALE_MODE_MANUAL, "ManualScale"=>$AxisBoundaries);

$myPicture->drawScale($scaleSettings);
 $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
 $myPicture->setFontProperties(array("FontName"=>"fonts/pf_arma_five.ttf","FontSize"=>6));
 $myPicture->drawLineChart(array("DisplayValues"=>TRUE,"DisplayColor"=>DISPLAY_AUTO));
 $myPicture->setShadow(FALSE);

 //deseneaza marimea 2 
 $myPicture->setGraphArea(500,60,670,190);
 $myPicture->drawFilledRectangle(500,60,670,190,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>10));
 $myPicture->drawScale(array("Pos"=>SCALE_POS_TOPBOTTOM,"DrawSubTicks"=>TRUE));
 $myPicture->setShadow(TRUE,array("X"=>-1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
 $myPicture->drawLineChart();
 $myPicture->setShadow(FALSE);

 // deseneaza legenda
 $myPicture->drawLegend(510,205,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));

 //rendereaza poza
 $myPicture->autoOutput("img/example.drawLineChart.png");

不幸的是，这使得整个页面呈现如下：（我正在上传一张图片，因为你需要一个帐户才能看到它）

我做错什么了吗？我在函数中使用了这段代码

---

而且，在WAMP示例中，这不起作用。有什么办法吗？

我设法做到了，并在这里发布了帮助他人的帖子

所以，我做了这个函数，但我编辑了粗体部分

然后，当我想叫它的时候，就像这样：

<?php grafice(); ?>

然后我可以做：

<img src="pictures/example.drawLineChart.png" />

现在我只需使用会话id更改图片名称，这样每个人都会有一个不同的图形；）希望这将有助于某人

PHP错误日志中有什么？没有。它是空的！错误报告正在进行吗？谢谢你的回复。很抱歉，我通过渲染图像，然后将其显示为
