散点图中缺少PHPExcel X轴标签

标签： time-series phpexcel scatter-plot axis-labels

我试图根据时间尺度创建一些包含多个系列的散点图，并且我有一些问题。请注意，每个系列的时间戳可能不同，因此需要使用散点图。

我会以相反的顺序回溯，但请考虑以下代码：

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

require_once __DIR__.'/phpexcel/Classes/PHPExcel.php';
require_once __DIR__.'/phpexcel/Classes/PHPExcel/Cell/AdvancedValueBinder.php';

PHPExcel_Cell::setValueBinder( new PHPExcel_Cell_AdvancedValueBinder() );

$objPHPExcel = new PHPExcel();
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->fromArray(
    array(
        array('','SERIES_1','SERIES_2'),
        array('2014-05-01 00:00:03',12574,''),
        array('2014-05-01 04:10:01',7347,''),
        array('2014-05-02 09:20:01',4175,''),
        array('2014-05-03 21:30:03',1045,''),
        array('2014-05-01 07:05:03','',8544),
        array('2014-05-02 12:15:01','',1324),
        array('2014-05-02 16:25:01','',6729),
        array('2014-05-03 15:35:03','',9420),
    )
);

$objWorksheet->getStyle('A2:A9')
    ->getNumberFormat()
    ->setFormatCode('yyyy-mm-dd hh:mm:ss'); 

//      Set the Labels for each data series we want to plot
//      Datatype
//      Cell reference for data

$dataseriesLabels = array(
    new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$B$1', NULL, 1),
    new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$C$1', NULL, 1),
);

//      Set the X-Axis Labels
$xAxisTickValues = array(
    new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$A$2:$A$9', NULL, 8),
    new PHPExcel_Chart_DataSeriesValues('String', 'Worksheet!$A$2:$A$9', NULL, 8),
);

//      Set the Data values for each data series we want to plot

    new PHPExcel_Chart_DataSeriesValues('Number', 'Worksheet!$C$2:$C$9', NULL, 8)
);

//      Build the dataseries
$series = new PHPExcel_Chart_DataSeries(
    PHPExcel_Chart_DataSeries::TYPE_SCATTERCHART,           // plotType
    NULL,                                                   // plotGrouping (Scatter charts don't have any grouping)
    range(0, count($dataSeriesValues)-1),                   // plotOrder
    $dataseriesLabels,                                      // plotLabel
    $xAxisTickValues,                                       // plotCategory
    $dataSeriesValues,                                      // plotValues
    NULL,                                                   // smooth line
    PHPExcel_Chart_DataSeries::STYLE_LINEMARKER             // plotStyle
);

//      Set the series in the plot area
$plotarea = new PHPExcel_Chart_PlotArea(NULL, array($series));
//      Set the chart legend
$legend = new PHPExcel_Chart_Legend(PHPExcel_Chart_Legend::POSITION_RIGHT, NULL, false);

$title = new PHPExcel_Chart_Title('CHART_TITLE');
$yAxisLabel = new PHPExcel_Chart_Title('Y_AXIS_TITLE');
$xAxisLabel = new PHPExcel_Chart_Title('X_AXIS_TITLE');

//      Create the chart
$chart = new PHPExcel_Chart(
    'chart1',               // name
    $title,                 // title
    $legend,                // legend
    $plotarea,              // plotArea
    true,                   // plotVisibleOnly
    0,                      // displayBlanksAs
    $xAxisLabel,            // xAxisLabel
    $yAxisLabel             // yAxisLabel
);

//      Set the position where the chart should appear in the worksheet
$chart->setTopLeftPosition('E3');
$chart->setBottomRightPosition('N18');

//      Add the chart to the worksheet
$objWorksheet->addChart($chart);

// Save Excel 2007 file
echo date('H:i:s') , " Write to Excel2007 format" , EOL;
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->setIncludeCharts(TRUE);
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
echo date('H:i:s') , " File written to " , str_replace('.php', '.xlsx', pathinfo(__FILE__, PATHINFO_BASENAME)) , EOL;

真正的数据最终将来自数据库，但现在我只是想在测试期间使事情发挥作用。这似乎有效，而我现在需要进行一些手动格式化（删除标记，更改线条粗细，刻度线上的位置轴，将数字格式更改为yyyy-mm-dd）图形似乎正确生成。

two_series

但是，如果我只使用一个数据系列，则图表会正确生成，但缺少x轴标签。刻度线位于正确的位置，只缺少标签。如下面的代码所示，我所做的就是注释掉第二组数据。

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

//      Build the dataseries

//      Create the chart

    $plotarea,              // plotArea
    true,                   // plotVisibleOnly
    0,                      // displayBlanksAs
    $xAxisLabel,            // xAxisLabel
    $yAxisLabel             // yAxisLabel
);

//      Set the position where the chart should appear in the worksheet
$chart->setTopLeftPosition('E3');
$chart->setBottomRightPosition('N18');

//      Add the chart to the worksheet
$objWorksheet->addChart($chart);

// Save Excel 2007 file
echo date('H:i:s') , " Write to Excel2007 format" , EOL;
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
echo date('H:i:s') , " File written to " , str_replace('.php', '.xlsx', pathinfo(__FILE__, PATHINFO_BASENAME)) , EOL;

如上所述，刻度线位于正确的位置，只缺少标签。

one_series

有关x轴标签为何不显示的任何想法？此外，如果我手动在Excel中创建散点图（插入＆gt;＆gt;图表＆gt;＆gt;散点图），我会得到一个带有x轴选项的时间刻度图表，以选择最小值，最大值，主要单位和次要单位，而图表来自PHPExcel似乎是一个类别/值类型，因为您只能选择刻度线和间隔单位之间的间隔。有没有办法改变这个？

编辑：忘记提及我已尝试同时使用PHPEx的1.8.0版本以及git上的最新开发分支。
