I need to remove the lines in my Scatter Chart. I tried modifying files in the PHPExcel’s Chart folder but none of my workarounds solved my problem. I think you’re supposed to set STYLE_MARKER in the array below but it doesn’t seem to work.
$series = new PHPExcel_Chart_DataSeries(
PHPExcel_Chart_DataSeries::TYPE_SCATTERCHART, // plotType
NULL, // plotGrouping (Scatter charts don't have any grouping)
range(0, count($dataSeriesValues)-1), // plotOrder
$dataseriesLabels, // plotLabel
$xAxisTickValues, // plotCategory
$dataSeriesValues, // plotValues
NULL, // smooth line
PHPExcel_Chart_DataSeries::STYLE_MARKER // plotStyle);
Any ideas?
