PHPExcel很棒,我非常喜歡將圖表添加到工作表的可能性。我玩過很多,但有一件事我無法完成。這是關於顯示在圖表的圖例中的數據系列的標籤: 我只得到這樣的結果: (請忽略不同的款式/顏色)PHPExcel DataSeries標籤沒有顯示
在這裏,我做了一個「小」的例子,也有人看什麼做錯了?

// create some sheet
$PHPExcel = new PHPExcel();
$sheet = $PHPExcel->getActiveSheet();
$sheet->fromArray([
// A B C D
['Month' ,'Data A', 'Data B', 'Data C'], // 1
['2015-08', 36.24, 65.23, 43.34], // 2
['2015-07', 54.15, 23.12, 28.53], // 3
['2015-06', 43.35, 56.43, 3.30], // 4
['2015-05', 62.56, 43.53, 32.63], // 5
['2015-04', 23.38, 3.34, 5.23] // 6
]);
$dataSeriesLabels = [
new \PHPExcel_Chart_DataSeriesValues('String','Data!$B$1',NULL,1), // B1
new \PHPExcel_Chart_DataSeriesValues('String','Data!$C$1',NULL,1), // C1
new \PHPExcel_Chart_DataSeriesValues('String','Data!$D$1',NULL,1) // D1
];
$dataSeriesValues = [
new \PHPExcel_Chart_DataSeriesValues('Number','Data!$B$2:$B$6',NULL,5), // B2-B6
new \PHPExcel_Chart_DataSeriesValues('Number','Data!$C$2:$C$6',NULL,5), // C2-C6
new \PHPExcel_Chart_DataSeriesValues('Number','Data!$D$2:$D$6',NULL,5), // D2-D6
];
$xAxisLabels = [
new \PHPExcel_Chart_DataSeriesValues('String','Data!$A$2:$A$6',NULL,5), // A2-A6
];
$dataSeries = new \PHPExcel_Chart_DataSeries(
\PHPExcel_Chart_DataSeries::TYPE_LINECHART,
\PHPExcel_Chart_DataSeries::GROUPING_STANDARD,
range(0, count($dataSeriesValues)-1),
$dataSeriesLabels,
$xAxisLabels,
$dataSeriesValues
);
$pa = new \PHPExcel_Chart_PlotArea(null, array($dataSeries));
$legend = new \PHPExcel_Chart_Legend(\PHPExcel_Chart_Legend::POSITION_RIGHT, NULL, false);
$chartTitle = new \PHPExcel_Chart_Title('Test');
$chart = new \PHPExcel_Chart('chart_'.uniqid(),$chartTitle,$legend,$pa,true,0,null,null);
$chart->setTopLeftPosition('A8');
$chart->setBottomRightPosition('K26');
$sheet->addChart($chart);
$objWriter = new PHPExcel_Writer_Excel2007($PHPExcel);
$objWriter->setPreCalculateFormulas(false);
$objWriter->setIncludeCharts(true);
$objWriter->save("php://output");
正如可以看到$dataSeriesLabels
被設置並連接到$dataSeries
,這是在$chart
$pa
(PlotArea)的一部分。我真的不明白爲什麼這不起作用,我很樂意提供任何建議。
