Some Questions about PHPExcel Charts

问题

I am using PHPExcel for generating charts in Excel Files. I have some question whoes answer I couldn't find even after lot of R&D those are

How can I show data labels to chart?
How can I control the width of bar charts?
How can I customize colors of bar charts?

I tried to show labels with layout class like :

  $layout = new PHPExcel_Chart_Layout();
  $layout->setShowVal(TRUE);

But no success. I have also explored DataSeries class and Chart Class but couldn't find any solution. Any body here who have already done such tasks, Please guide.

Best Regards.

With this:

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

$series = new PHPExcel_Chart_DataSeries(
    PHPExcel_Chart_DataSeries::TYPE_BARCHART,       // plotType
    PHPExcel_Chart_DataSeries::GROUPING_STANDARD,   // plotGrouping
    range(0, count($dataSeriesValues)-1),           // plotOrder
    $dataseriesLabels,                              // plotLabel
    $xAxisTickValues,                               // plotCategory
    $dataSeriesValues                               // plotValues
);

you can define the dataseriesLabels to use in your chart
PHPExcel set default Column Width
PhpExcel Bar Chart
