[PHP][pChart] Pobieranie danych z pliku txt Opcje

[fisherek]

Witam, wszystkich!

Na podstawie przykładowych wykresów staram się stworzyć swój. Nie mogę sobie poradzić z jakimś błędem odnośnie wczytywania danych z pliku tekstowego.
Mój kod:

[PHP] pobierz, plaintext 
 /* CAT:Area Chart */
 
 /* pChart library inclusions */
 include("../class/pData.class.php");
 include("../class/pDraw.class.php");
 include("../class/pImage.class.php");
 
 /* Create and populate the pData object */
 $MyData = new pData();  
 
 $nazwa_pliku = "xy.txt";
 if (is_readable($nazwa_pliku))
  {
   if ($plik = fopen($nazwa_pliku, "r"))
     {
      $dane = file($nazwa_pliku);      
      if ($dane === FALSE) echo "Odczyt danych z pliku nie powiódł się...";
	  else 
		for($i=0; $i<= 1000; $i++)
		{
			$MyData->addPoints($dane[$i],"Inbound");
		}
		fclose($plik);
      } else echo "Nie mogę nawiązać połączenia z plikiem...";
  } else echo "Z pliku nie można odczytać informacji lub nie istnieje..."; 
 
 /* Create the pChart object */
 $myPicture = new pImage(700,230,$MyData);
 
 /* Turn of Antialiasing */
 $myPicture->Antialias = FALSE;
 
 /* Add a border to the picture */
 $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
 
 /* Write the chart title */ 
 $myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));
 $myPicture->drawText(150,35,"Average temperature",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
 
 /* Set the default font */
 $myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>6));
 
 /* Define the chart area */
 $myPicture->setGraphArea(60,40,650,200);
 
 /* Draw the scale */
 $scaleSettings = array("XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
 $myPicture->drawScale($scaleSettings);
 
 /* Write the chart legend */
 $myPicture->drawLegend(540,20,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
 
 /* Turn on Antialiasing */
 $myPicture->Antialias = TRUE;
 
 /* Draw the area chart */
 $myPicture->drawAreaChart();
 
 /* Render the picture (choose the best way) */
 $myPicture->autoOutput("pictures/example.drawAreaChart.simple.png");

a to oryginalny kod powyższego wykresu:

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

 /* Create and populate the pData object */
 $MyData = new pData();  
 $MyData->addPoints(array(4,2,10,12,8,3),"Probe 1");
 $MyData->addPoints(array(3,12,15,8,5,5),"Probe 2");
 $MyData->addPoints(array(2,7,5,18,15,22),"Probe 3");
 $MyData->setSerieTicks("Probe 2",4);
 $MyData->setAxisName(0,"Temperatures");
 $MyData->addPoints(array("Jan","Feb","Mar","Apr","May","Jun"),"Labels");
 $MyData->setSerieDescription("Labels","Months");
 $MyData->setAbscissa("Labels");
 
 /* Create the pChart object */
 $myPicture = new pImage(700,230,$MyData);

 $myPicture->Antialias = FALSE;
 
 /* Add a border to the picture */
 $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
 
 /* Write the chart title */ 
 $myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));
 $myPicture->drawText(150,35,"Average temperature",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
