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 
  1.  /* CAT:Area Chart */
  2.  
  3.  /* pChart library inclusions */
  4.  include("../class/pData.class.php");
  5.  include("../class/pDraw.class.php");
  6.  include("../class/pImage.class.php");
  7.  
  8.  /* Create and populate the pData object */
  9.  $MyData = new pData();  
  10.  
  11.  $nazwa_pliku = "xy.txt";
  12.  if (is_readable($nazwa_pliku))
  13.   {
  14.    if ($plik = fopen($nazwa_pliku, "r"))
  15.      {
  16.       $dane = file($nazwa_pliku);      
  17.       if ($dane === FALSE) echo "Odczyt danych z pliku nie powiódł się...";
  18. 	  else 
  19. 		for($i=0; $i<= 1000; $i++)
  20. 		{
  21. 			$MyData->addPoints($dane[$i],"Inbound");
  22. 		}
  23. 		fclose($plik);
  24.       } else echo "Nie mogę nawiązać połączenia z plikiem...";
  25.   } else echo "Z pliku nie można odczytać informacji lub nie istnieje..."; 
  26.  
  27.  /* Create the pChart object */
  28.  $myPicture = new pImage(700,230,$MyData);
  29.  
  30.  /* Turn of Antialiasing */
  31.  $myPicture->Antialias = FALSE;
  32.  
  33.  /* Add a border to the picture */
  34.  $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
  35.  
  36.  /* Write the chart title */ 
  37.  $myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>11));
  38.  $myPicture->drawText(150,35,"Average temperature",array("FontSize"=>20,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));
  39.  
  40.  /* Set the default font */
  41.  $myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>6));
  42.  
  43.  /* Define the chart area */
  44.  $myPicture->setGraphArea(60,40,650,200);
  45.  
  46.  /* Draw the scale */
  47.  $scaleSettings = array("XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
  48.  $myPicture->drawScale($scaleSettings);
  49.  
  50.  /* Write the chart legend */
  51.  $myPicture->drawLegend(540,20,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
  52.  
  53.  /* Turn on Antialiasing */
  54.  $myPicture->Antialias = TRUE;
  55.  
  56.  /* Draw the area chart */
  57.  $myPicture->drawAreaChart();
  58.  
  59.  /* Render the picture (choose the best way) */
  60.  $myPicture->autoOutput("pictures/example.drawAreaChart.simple.png");
