Question

我尝试使用TeeChart的右轴用于PHP。我知道我们需要将有效系列链接到两个垂直轴。事实上，我已经在Steema网站上尝试了使用自定义轴演示的简单测试。我剪切并粘贴了演示并尝试将其导出为javascript而不是渲染它。我用这段代码导出到javascript：

echo  $tChart1->getChart()->getExport()->getImage()->getJavaScript()->Render()->toString();

Here是2个渲染并排的快照（很抱歉把它放在链接中，这个论坛不允许我发布图片......）

有没有办法让右轴显示出口？

编辑：以下是您身边测试的代码：

<?php 
    //Includes 
    include "../../../sources/TChart.php"; 

    $chart1 = new TChart(600,450); 
    $chart1->getChart()->getHeader()->setText("Custom Axes Demo"); 
    $chart1->getAspect()->setView3D(false); 

    $line1 = new Line($chart1->getChart()); 
    $line2 = new Line($chart1->getChart()); 
    $line1->setColor(Color::RED()); 
    $line2->setColor(Color::GREEN()); 
    $chart1->addSeries($line1); 
    $chart1->addSeries($line2); 

    // Speed optimization 
    $chart1->getChart()->setAutoRepaint(false); 

    for($t = 0; $t <= 10; ++$t) { 
      $line1->addXY($t, (10 + $t), Color::RED()); 
      if($t > 1) { 
        $line2->addXY($t, $t, Color::GREEN()); 
      } 
    }  

    $chart1->getAxes()->getLeft()->setStartPosition(0); 
    $chart1->getAxes()->getLeft()->setEndPosition(50);         
    $chart1->getAxes()->getLeft()->getAxisPen()->color = Color::RED(); 
    $chart1->getAxes()->getLeft()->getTitle()->getFont()->setColor(Color::RED()); 
    $chart1->getAxes()->getLeft()->getTitle()->getFont()->setBold(true); 
    $chart1->getAxes()->getLeft()->getTitle()->setText("1st Left Axis"); 

    $chart1->getAxes()->getTop()->getLabels()->setAngle(45); 
    $chart1->getAxes()->getTop()->getTitle()->getFont()->setColor(Color::YELLOW()); 
    $chart1->getAxes()->getTop()->getTitle()->getFont()->setBold(true); 

    $chart1->getAxes()->getBottom()->getLabels()->setAngle(0); 
    $chart1->getAxes()->getRight()->getLabels()->setAngle(45); 
    $chart1->getAxes()->getBottom()->getTitle()->getFont()->setColor(new Color(255,25,25)); 
    $chart1->getAxes()->getBottom()->getTitle()->getFont()->setBold(true); 
    $chart1->getAxes()->getRight()->getTitle()->getFont()->setColor(Color::BLUE()); 
    $chart1->getAxes()->getRight()->getTitle()->getFont()->setBold(true); 
    $chart1->getAxes()->getRight()->getTitle()->setText("OtherSide Axis"); 
    $chart1->getAxes()->getRight()->getLabels()->getFont()->setColor(Color::BLUE()); 
    $chart1->getAxes()->getRight()->getAxisPen()->setColor(Color::BLUE());         

    $chart1->getAxes()->getTop()->getTitle()->setText("Top Axis"); 
    $chart1->getAxes()->getBottom()->getTitle()->setText("Bottom Axis"); 

    $line1->setHorizontalAxis(HorizontalAxis::$BOTH); 
    $line1->setVerticalAxis(VerticalAxis::$BOTH); 

    $axis1 = new Axis(false, false, $chart1->getChart()); 
    $chart1->getAxes()->getCustom()->add($axis1); 
    $line2->setCustomVertAxis($axis1); 
    $axis1->setStartPosition(50); 
    $axis1->setEndPosition(100); 
    $axis1->getTitle()->getFont()->setColor(Color::GREEN());         
    $axis1->getTitle()->getFont()->setBold(true); 
    $axis1->getTitle()->setText("Extra Axis"); 
    $axis1->getTitle()->setAngle(90); 
    $axis1->setRelativePosition(20); 
    $axis1->getAxisPen()->setColor(Color::GREEN()); 
    $axis1->getGrid()->setVisible(false); 

    echo  $tChart1->getChart()->getExport()->getImage()->getJavaScript()->Render()->toString();?>

我修改了测试页的末尾，以便在同一页面上显示HTML5和PHP图表：

echo  $chart1->getChart()->getExport()->getImage()->getJavaScript()->Render()->toString();
$chart1->render("chart1.png");
$rand=rand();
print '<img src="chart1.png?rand='.$rand.'">';

然后，我修改了TeeChart PHP源代码以导出自定义轴和赋值。

现在看起来像这样：

请发送邮件至“info@steema.com”，我们将向您发送修改后的单位（JavaScriptExport.php）。
