I'm working with PHPExcel in order to export Excel chart with Bar Chart.
I can export the chart with the default layout as this image:
But, I want to make the axis layout at the top of chart and reverse the Y-axis as this image:
How can I do that?

After researching the code I found that it is possible to reverse the axis:
$yAxis = new \PHPExcel_Chart_Axis(); $yAxis->setsetAxisOptionsProperties( \PHPExcel_Chart_Axis::AXIS_LABELS_NEXT_TO, null, null, \PHPExcel_Properties::ORIENTATION_REVERSED ); $chart = new \PHPExcel_Chart( "Chart1", $titile, $legend, $plotArea, true, '0', null, null, null, //xAxis parameter if you want to reverse the x axis $yAxis );NOTE: If you set the series direction to columns instead of bars
$series = new \PHPExcel_Chart_DataSeries(....); $series->setPlotDirection(\PHPExcel_Chart_DataSeries::DIRECTION_COL);the axis are reversed, so what you set as options for the Y-axis will be applied to the X-axis and the opposite.
However reversing the axis cannot be achieved by other methods expected to work:
$chart->getChartAxisY()->setAxisOrientation(\PHPExcel_Properties::ORIENTATION_REVERSED);or
$yAxis = new \PHPExcel_Chart_Axis(); $yAxis->setAxisOrientation(\PHPExcel_Properties::ORIENTATION_REVERSED); $chart = new \PHPExcel_Chart( "Chart1", $titile, $legend, $plotArea, true, '0', null, null, null, //xAxis parameter if you want to reverse the x axis $yAxis );
