我正在使用PHPPowerPoint导出.ppt文件，使用PHP. 到目前为止，当我想从条形图中删除图例时，我是成功的。
生成条形图的代码是：
$chart1 = new Bar();
$series = new Series('City Distribution', $timeseries);
$series->setShowSeriesName(false);
$series->setShowValue(true);
$series->getFill()->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FF1dd2af'));
$chart1->addSeries($series);
$gFill = new Fill();
$gFill->setFillType(Fill::FILL_GRADIENT_PATH)->setRotation(90)->setStartColor(new Color( 'FF1dd2af' ))->setEndColor(new Color( 'FFFFFFFF' ));
$oFill = new Fill();
$oFill->setFillType(Fill::FILL_SOLID)->setStartColor(new Color('FFFFFFFF'));
$oShadow = new Shadow();
$oShadow->setVisible(true)->setDirection(45)->setDistance(10);
// Create a shape (chart)
$shape = $currentSlide->createChartShape();
//$shape->getAlignment()->setVertical( Alignment::VERTICAL_TOP );
$shape->getTitle()->setVisible(false);
$shape->setName('City Distribution')->setResizeProportional(false)->setHeight(300)->setWidth(250)->setOffsetX(25)->setOffsetY(200);
$shape->setFill($oFill);
$shape->getTitle()->setText('City Distribution');
$shape->getTitle()->getFont()->setItalic(true);
$shape->getPlotArea()->getAxisX()->setTitle('City');
$shape->getPlotArea()->getAxisY()->setTitle('Number of Users');
$shape->getPlotArea()->setType($chart1);
$shape->getLegend()->getBorder()->setLineStyle(Border::LINE_SINGLE);
$shape->getLegend()->getFont()->setItalic(true);
这工作得很好，但它放置了一个图例框，我想删除它。任何想法？
