如何在pChart中标记x轴

Question

我正在尝试命名我的x轴（见图）。

如您所见，没有打印x轴名称。但是，由于以下这一行，我的代码应该打印一个：$MyData->setSerieDescription("Labels","Range of Data");，除非我误解了用法。

码：

 /* 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();  
 $MyData->addPoints(array($LT50,$GT50_LT100,$GT100_LT150,$GT150_LT200,$GT200_LT250,$GT250_LT300,$GT300_LT350,$GT350_LT400,$GT400_LT450,$GT450),"Probe 3");
 $MyData->setSerieWeight("Probe 3",2);
 $MyData->setAxisName(0,"Number of Occurrences");;
 $MyData->addPoints(array("Diff < 50","50 > Diff < 100","100 > Diff < 150","150 > Diff < 200","200 > Diff < 250","250 > Diff < 300","300 > Diff < 350", "350 > Diff < 400", "400 > Diff < 450", "Diff > 450"),"Labels");
 $MyData->setSerieDescription("Labels","Range of Data");
 $MyData->setAbscissa("Labels");


 /* Create the pChart object */
 $myPicture = new pImage(1500,690,$MyData);

 /* Turn of Antialiasing */
 $myPicture->Antialias = FALSE;

 /* Add a border to the picture */
 $myPicture->drawRectangle(0,0,1440,675,array("R"=>0,"G"=>0,"B"=>0));

 /* Write the chart title */ 
 $myPicture->setFontProperties(array("FontName"=>"../fonts/Forgotte.ttf","FontSize"=>20));
 $myPicture->drawText(250,35,"Time Diff Between TRWire Job Created and Crew Dispatched",array("FontSize"=>15,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));

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

 /* Define the chart area */
 $myPicture->setGraphArea(60,40,1400,600);

 /* Draw the scale */
$AxisBoundaries = array(0=>array("Min"=>0,"Max"=>$max));
 $scaleSettings = array("Mode"=>SCALE_MODE_MANUAL, "LabelRotation"=>30, "ManualScale"=>$AxisBoundaries, "XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE );
 $myPicture->drawScale($scaleSettings);

 /* Turn on Antialiasing */
 $myPicture->Antialias = TRUE;

 /* Draw the line chart */
 $myPicture->drawLineChart();

 /* Render the picture (choose the best way) */
 $myPicture->autoOutput("./pChart/examples/pictures/example.drawLineChart.simple.png");

这个问题困扰了我。我很晚才起床，诊断只是让我的图表显示出来。

与缺少的X轴标题相关，我终于发现在源目录中使用$myData->setAbscissaName("Time of Reading");grepping对我有用。太神奇了。

他们的文档很差。我什至复制并粘贴了带有标题x轴的示例脚本（该脚本在复制和粘贴时从未起作用），结果它们也没有标题。非常烦躁。
