Question

我正在使用PHPExcel构建包含多个图表的Excel工作表，并尝试自定义它们。我只剩下3个未解决的问题： 1.我希望图表没有边框。 2.我想改变图线的颜色。 3.我想改变图形区域内图形的位置。至于现在这是我构建图表的方式：

$xAxisTickValues = $TruexAxisTickValues;
$series = new PHPExcel_Chart_DataSeries(
  PHPExcel_Chart_DataSeries::TYPE_LINECHART,        // plotType
  PHPExcel_Chart_DataSeries::GROUPING_STANDARD,     // plotGrouping
  range(0, 10),                                 // plotOrder
  null,                                         // plotLabel
  $xAxisTickValues,                                 // plotCategory
  $values                                           // plotValues
);
$series->setPlotDirection(PHPExcel_Chart_DataSeries::DIRECTION_COL);
$plotarea = new PHPExcel_Chart_PlotArea(null, array($series));
$chart = new PHPExcel_Chart(
  'chart1',                                       // name
  null,                                           // title
  null,                                         // legend
  $plotarea,                                      // plotArea
  true,                                           // plotVisibleOnly
  0,                                              // displayBlanksAs
  null,                                           // xAxisLabel
  null                                            // yAxisLabel
);
$chart->setTopLeftPosition('C5' );
$chart->setBottomRightPosition('J11' );
$sheet->addChart($chart);

有没有办法自定义图表？

Answer 1

正如Rzangue所说，PHPExcel目前不提供这样做的简单方法，但是，如果您不介意对使用PHPExcel创建的所有图形进行硬编码，您可以将下面建议的更改发送到您的PHPExcel / Classes / Writer / Excel2007 / Chart.php文件。

要改变图表的边框颜色，请在公共函数writeChart（）中添加：

$cBorderColor = "000000";
$objWriter->startElement('c:spPr');
    $objWriter->startElement('a:ln');
        $objWriter->startElement('a:solidFill');
            $objWriter->startElement('a:srgbClr');
                $objWriter->writeAttribute('val',$cBorderColor);
            $objWriter->endElement();
        $objWriter->endElement();
    $objWriter->endElement();
 $objWriter->endElement();

后：

    $objWriter->startElement('c:showDLblsOverMax');
        $objWriter->writeAttribute('val', 0);
    $objWriter->endElement();

$objWriter->endElement();

但之前：

$this->_writePrintSettings($objWriter);

应该在Chart.php文件的第106行附近。

显然用您希望成为图表边框颜色的任何网页颜色替换“000000”。要完全删除边框颜色，请插入：

$objWriter->startElement('c:spPr');
    $objWriter->startElement('a:ln');
        $objWriter->startElement('a:noFill');
        $objWriter->endElement();
    $objWriter->endElement();
$objWriter->endElement();

代替。

接下来，要更改图表中绘图区域的位置，请在Chart.php文件中向下滚动到私有函数_writeLayout（）。

除了打开/关闭括号{}之外，删除函数中的所有代码。在函数中，添加：

$layoutTarget = "inner";
$xMode = "edge";
$yMode = "edge";
$xOffset = 0.1;  //The left margin in percentage of graph width.
$yOffset = 0.1;  //The top margin in percentage of graph width.
$paWidth = 0.9;  //The percentage width of the plot area relative to the graph width;
$paHeight = 0.9; //The percentage height of the plot area relative to the graph height;

$objWriter->startElement('c:layout');
    $objWriter->startElement('c:manualLayout');
        $objWriter->startElement('c:layoutTarget');
            $objWriter->writeAttribute('val',$layoutTarget);
        $objWriter->endElement();
        $objWriter->startElement('c:xMode');
            $objWriter->writeAttribute('val',$xMode);
        $objWriter->endElement();
        $objWriter->startElement('c:yMode');
            $objWriter->writeAttribute('val',$yMode);
        $objWriter->endElement();
        $objWriter->startElement('c:x');
            $objWriter->writeAttribute('val',$xOffset);
        $objWriter->endElement();
        $objWriter->startElement('c:y');
            $objWriter->writeAttribute('val',$yOffset);
        $objWriter->endElement();
        $objWriter->startElement('c:w');
            $objWriter->writeAttribute('val',$paWidth);
        $objWriter->endElement();
        $objWriter->startElement('c:h');
            $objWriter->writeAttribute('val',$paHeight);
        $objWriter->endElement();
    $objWriter->endElement(); 
$objWriter->endElement();

然后您可以根据需要调整x / y偏移和w / h。

要控制/更改每个数据系列的颜色，请执行以下操作：

private function _writePlotGroup()

之前：

foreach($plotSeriesOrder as $plotSeriesIdx => $plotSeriesRef) {

添加：

$ci=-1;
$colorNDX=array();
$colorNDX[0] = "111111";
$colorNDX[1] = "222222";
$colorNDX[2] = "333333";
$colorNDX[3] = "444444";
$colorNDX[4] = "555555";
$colorNDX[5] = "666666";
$colorNDX[6] = "777777";

依此类推，确保为所有系列数据添加足够的颜色索引，并明显将111111,222222,333333更改为您喜欢的网页颜色。

此外，在：

之后

foreach($plotSeriesOrder as $plotSeriesIdx => $plotSeriesRef) {

添加：

$ci++;

之后：

//  Labels
$plotSeriesLabel = $plotGroup->getPlotLabelByIndex($plotSeriesRef);
if ($plotSeriesLabel && ($plotSeriesLabel->getPointCount() > 0)) {
    $objWriter->startElement('c:tx');
    $objWriter->startElement('c:strRef');
        $this->_writePlotSeriesLabel($plotSeriesLabel, $objWriter);
    $objWriter->endElement();
$objWriter->endElement();
}

添加：

$objWriter->startElement('c:spPr');
    $objWriter->startElement('a:solidFill');
        $objWriter->startElement('a:srgbClr');
            $objWriter->writeAttribute('val',$colorNDX[$ci]);
        $objWriter->endElement();
    $objWriter->endElement();
$objWriter->endElement();

如果这有帮助，请告诉我。同样，这些更改将应用于PHPExcel生成的所有图表，但是，一些好的if语句应该足以使每个图表类型的更改更加动态。

Answer 2

使用LineCharts时，添加IIIOXIII的代码，特别是下面的代码块，导致Excel 2007出现错误

$objWriter->startElement('c:spPr');
 $objWriter->startElement('a:solidFill');
  $objWriter->startElement('a:srgbClr');
   $objWriter->writeAttribute('val',$colorNDX[$ci]);
  $objWriter->endElement();
 $objWriter->endElement();
$objWriter->endElement();

首先在上面的块

周围添加以下条件语句

if ($groupType !== PHPExcel_Chart_DataSeries::TYPE_LINECHART && $groupType !== PHPExcel_Chart_DataSeries::TYPE_STOCKCHART) {
    // above code block
}

然后在大约十几行之后阻止代码读取

if ($groupType == PHPExcel_Chart_DataSeries::TYPE_STOCKCHART) {
  $objWriter->startElement('a:noFill');
  $objWriter->endElement();
}

添加以下内容

$objWriter->startElement('a:solidFill');
  $objWriter->startElement('a:srgbClr');
   $objWriter->writeAttribute('val',$colorNDX[$ci])
  $objWriter->endElement();
$objWriter->endElement();

这样可以防止Excel出错并允许您使用彩色线图

Answer 3

在我的情况下，我想要更改为饼图的原始颜色，我能够通过编辑PHPExcel_Writer_Excel2007_Theme类而无需编辑其原始作者 Excel2007 来实现此目的：< / p>

复制Excel2007文件夹，然后将其放在具有不同名称的同一文件夹中，例如'Excel2007Custom'
打开Excel2007Custom文件夹中的所有类，并重命名这些类，例如

PHPExcel_Writer_Excel2007_Chart将成为PHPExcel_Writer_Excel2007Custom_Chart

PHPExcel_Writer_Excel2007_Comments将成为PHPExcel_Writer_Excel2007Custom_Comments

等等。

复制Excel2007.php个文件并将其放在具有不同名称的同一文件夹中，例如'Excel2007Custom.php'
打开班级文件Excel2007Custom.php并：
- 将PHPExcel_Writer_Excel2007中的类重命名为PHPExcel_Writer_Excel2007Custom
- 更改构造函数中的数组$writerPartsArray值。

从：

    $writerPartsArray = array(
        'stringtable'   => 'PHPExcel_Writer_Excel2007_StringTable',
        'contenttypes'  => 'PHPExcel_Writer_Excel2007_ContentTypes',
        'docprops'      => 'PHPExcel_Writer_Excel2007_DocProps',
        'rels'          => 'PHPExcel_Writer_Excel2007_Rels',
        'theme'         => 'PHPExcel_Writer_Excel2007_Theme',
        'style'         => 'PHPExcel_Writer_Excel2007_Style',
        'workbook'      => 'PHPExcel_Writer_Excel2007_Workbook',
        'worksheet'     => 'PHPExcel_Writer_Excel2007_Worksheet',
        'drawing'       => 'PHPExcel_Writer_Excel2007_Drawing',
        'comments'      => 'PHPExcel_Writer_Excel2007_Comments',
        'chart'         => 'PHPExcel_Writer_Excel2007_Chart',
        'relsvba'       => 'PHPExcel_Writer_Excel2007_RelsVBA',
        'relsribbonobjects' => 'PHPExcel_Writer_Excel2007_RelsRibbon'
     );

为：

    $writerPartsArray = array(
        'stringtable'   => 'PHPExcel_Writer_Excel2007Custom_StringTable',
        'contenttypes'  => 'PHPExcel_Writer_Excel2007Custom_ContentTypes',
        'docprops'      => 'PHPExcel_Writer_Excel2007Custom_DocProps',
        'rels'          => 'PHPExcel_Writer_Excel2007Custom_Rels',
        'theme'         => 'PHPExcel_Writer_Excel2007Custom_Theme',
        'style'         => 'PHPExcel_Writer_Excel2007Custom_Style',
        'workbook'      => 'PHPExcel_Writer_Excel2007Custom_Workbook',
        'worksheet'     => 'PHPExcel_Writer_Excel2007Custom_Worksheet',
        'drawing'       => 'PHPExcel_Writer_Excel2007Custom_Drawing',
        'comments'      => 'PHPExcel_Writer_Excel2007Custom_Comments',
        'chart'         => 'PHPExcel_Writer_Excel2007Custom_Chart',
        'relsvba'       => 'PHPExcel_Writer_Excel2007Custom_RelsVBA',
        'relsribbonobjects' => 'PHPExcel_Writer_Excel2007Custom_RelsRibbon'
     );

然后编辑PHPExcel_Writer_Excel2007Custom_Theme类$_colourScheme类属性
最后我打电话给班级作家：

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007Custom');

Answer 4

花了几个小时看看 - ＆gt;改变图形的颜色。

打开文件Theme.php \ PHPExcel \类\ PHPExcel \作家\ Excel2007中\ Theme.php

在底部，你会发现：

private function writeColourScheme($objWriter)
{
    foreach (self::$colourScheme as $colourName => $colourValue) {
        $objWriter->startElement('a:'.$colourName);

            $objWriter->startElement('a:srgbClr');
                $objWriter->writeAttribute('val', $colourValue);
            $objWriter->endElement();

        $objWriter->endElement();
    }
}

相反，你必须放置这个：

private function writeColourScheme($objWriter)
{
    $ci = 0;
    $colorNDX=array();
    $colorNDX[0] = "a09a9a";
    $colorNDX[1] = "1b1b1b";
    $colorNDX[2] = "350d0d";
    $colorNDX[3] = "ff0000";
    $colorNDX[4] = "b9a8a8";
    $colorNDX[5] = "a09a9a";
    $colorNDX[6] = "ff0000";
    $colorNDX[7] = "a09a9a";
    $colorNDX[8] = "1b1b1b";
    $colorNDX[9] = "ff0000";
    $colorNDX[10] = "1b1b1b";

    foreach (self::$colourScheme as $colourName => $colourValue) {

        $objWriter->startElement('a:'.$colourName);
            $objWriter->startElement('a:srgbClr');
            $objWriter->writeAttribute('val', $colorNDX[$ci]);
            $objWriter->endElement();

            $ci++;
        $objWriter->endElement();
    }
}

希望这对你有用： - ）

当前版本：PHPExcel 1.7.9不允许执行任何操作。

Answer 6

在饼图中我发现PHPExcel只从serie写了1个数据点，3号（为什么不是5，或1，我不知道=）），因此如果你想自定义馅饼的颜色，你必须编辑函数_writePlotGroup中的文件类/ PHPExcel / Writer / Excel2007 / Charts.php

//Getting datapoints and  loop around $objWrite->startElement(c:dPt) 
 $plotSeriesValues = $plotGroup->getPlotValuesByIndex($plotSeriesRef);
if (($groupType == PHPExcel_Chart_DataSeries::TYPE_PIECHART) ||
                    ($groupType == PHPExcel_Chart_DataSeries::TYPE_PIECHART_3D) ||
                    ($groupType == PHPExcel_Chart_DataSeries::TYPE_DONUTCHART)) {


foreach($plotSeriesValues->getDataValues() as $plotSeriesKey => $plotSeriesValue) {
...
   /*instead of $objWriter->writeAttribute('val', 3); put after
 $objWriter->startElement('c:dPt');
                        $objWriter->startElement('c:idx');*/
$objWriter->writeAttribute('val', $plotSeriesKey);
//according to previous answer, find the color of pie by index of datapoint in colorNDX

$objWriter->writeAttribute('val',$colorNDX[$plotSeriesKey]);
