Question

到目前为止，我已经通过PHPExcel成功地将数据从Mysql导出到Excel中，制作了我的表格，格式化了，而且一切都很笨拙。

然而，到目前为止，从所述表格制作图表的任何尝试都失败了。不仅仅是在Google搜索结束几天之后，我还没有找到关于如何从MySQL填充图表值的简单示例/教程。

这一切归结为：

Taken from https://github.com/affinitybridge/phpexcel/blob/master/Tests/33chartcreate-pie.php

/** PHPExcel */
include 'PHPExcel.php';
$objPHPExcel = new PHPExcel();
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->fromArray(
    array(
        array('',   2010,   2011,   2012),
        array('Q1',   12,   15,     21),
        array('Q2',   56,   73,     86),
        array('Q3',   52,   61,     69),
        array('Q4',   30,   32,     0),
    )
);

我该如何填充$ objWorksheet-＆gt; fromArray来自a）Mysql或b）excel。

如果是SQL，我需要为我数据库中的所有表运行此查询。

$ sql =＆＃34; SELECT Functional_Area，Passed__Status，Blocked__Status，Failed__Status FROM $ tbl_name WHERE 1;

上下文：我有几个功能区，每个功能区在Passed / Failed / Blocked中都有不同的值。每个功能区域需要1个图表。平均而言，每张表有14个功能区。

然后，我会为每个功能区构建一个饼图（或条形图，我并不挑剔）。

选项2）Excel

由于我已经在excel中说过数据，我需要填充以下数据：

同样，每个ROW（ROW 5（FA = EPG）的1个图形将是1个图形，ROW 6（FA = VOD）将是另一个图形等等。）

这必须在每个工作表中重复...

到目前为止我的尝试在下面，这为每个工作表（这很好）产生了一个图表，但是它是空的（不好）。

foreach (glob("*.xls") as $f) 
{
    $inputFileName = $f;    
    echo "Found $inputFileName <br/>";  
}


//  Read your Excel workbook

        $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
        $objReader = PHPExcel_IOFactory::createReader($inputFileType);
        $objPHPExcel = $objReader->load($inputFileName);
        $i = 0;
        foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) 
            {
                $arrayData[$worksheet->getTitle()] = $worksheet->toArray();
                echo "Title: ".$worksheet->getTitle()."<br/>"; 
                $wsTitle = $worksheet->getTitle();

                $objWorksheet = $objPHPExcel->setActiveSheetIndexByName($wsTitle);

                $highestRow         = $worksheet->getHighestRow(); // e.g. 10
                $endofData = $highestRow -1;
                $highestColumn      = $worksheet->getHighestColumn(); // e.g 'F'
                $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
                $colNumberStart = PHPExcel_Cell::columnIndexFromString("D");
                $BeforeTOT = $colNumberStart - 2;            
                $TOT = $colNumberStart - 1;             
                echo "Highest Row is ==> $highestRow <br/>End of Data - header is $endofData <br/> Highest Col is ==>  $highestColumn <br/> Start col is ==> $colNumberStart and Highest Col end is ==> $highestColumnIndex <br/>";

Answer 1

费拉斯，我有更多的调查，并得出了一些答案。

一个。如果数据在Excel上，则无需从Mysql查询湾这是一个有效的代码片段，100％的时间用于填充之前已填充的工作表的堆积条形图：

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

                    new PHPExcel_Chart_DataSeriesValues('String', 'report!$G$4', NULL, 4)    //  Jan to Dec
                );

                //  Set the X-Axis Labels

                $xAxisTickValues = array(

                    new PHPExcel_Chart_DataSeriesValues('Number', 'report!$F$5:$F$20', NULL, 16),
                    new PHPExcel_Chart_DataSeriesValues('Number', 'report!$G$5:$G$20', NULL, 16)
                );

                //  Build the dataseries
                $series1 = new PHPExcel_Chart_DataSeries(
                    PHPExcel_Chart_DataSeries::TYPE_BARCHART,        // plotType
                    PHPExcel_Chart_DataSeries::GROUPING_STACKED,    // plotGrouping
                    range(0, count($dataSeriesValues1)-1),          // plotOrder
                    $dataseriesLabels1,                             // plotLabel
                    $xAxisTickValues,                               // plotCategory
                    $dataSeriesValues1                              // plotValues
                );
                //  Set additional dataseries parameters
                //      Make it a vertical column rather than a horizontal bar graph
                $series1->setPlotDirection(PHPExcel_Chart_DataSeries::DIRECTION_COL);

                //  Set the series in the plot area
                $plotarea = new PHPExcel_Chart_PlotArea(NULL, array($series1));
                //  Set the chart legend
                $legend = new PHPExcel_Chart_Legend(PHPExcel_Chart_Legend::POSITION_RIGHT, NULL, false);

                $title = new PHPExcel_Chart_Title('Average Weather Chart for Crete');


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

                //  Set the position where the chart should appear in the worksheet
                $chart->setTopLeftPosition('F2');
                $chart->setBottomRightPosition('O16');

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




                // Instantiate a Writer to create an OfficeOpenXML Excel .xlsx file
                $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); 
                $objWriter->setIncludeCharts(true);

d。因此，要自动创建图形，过程将是： D1。打开w / e工作表，您需要从中获取数据 D2。读取或硬编码标签，x和y轴的值 D3。创建Chart元素 D4。发布所述元素w / e是理想的。

希望这可以帮助其他一些可怜的编码人员解决PHPExcel + Graphs的麻烦

我正在尝试动态构建数组，但有点失败。

  Fellas, question.

我现在正试图动态填充它，换句话说，构建：

   $dataseriesLabels1 = "array(";

   foreach ($Labels as $k => $s) 
   {
     echo "Parsing $s <br/>";
     $dataseriesLabels1 .= "new PHPExcel_Chart_DataSeriesValues('String', ".$s.", NULL, 4),";
     // echo "We have $dataseriesLabels1 in this loop <br/>";
   }
   $dataseriesLabels1 = rtrim($dataseriesLabels1, "," );
   $dataseriesLabels1 .= ");";

    echo "BUilt : $dataseriesLabels1 <br/>";

这一切都很好，因为它为我创造了：

   array(new PHPExcel_Chart_DataSeriesValues('String', 'Sprint!$D$4:$D$16', NULL, 4),new PHPExcel_Chart_DataSeriesValues('String', 'Sprint!$E$4:$E$16', NULL, 4),new PHPExcel_Chart_DataSeriesValues('String', 'Sprint!$F$4:$F$16', NULL, 4),new PHPExcel_Chart_DataSeriesValues('String', 'Sprint!$G$4:$G$16', NULL, 4),new PHPExcel_Chart_DataSeriesValues('String', 'Sprint!$H$4:$H$16', NULL, 4));

不幸的是，这被解释为字符串，而不是数组，因此图表生成失败：/
