1) What are the options for "DisplayBlanksAs"
$chart1 = new PHPExcel_Chart(
'chart1', // name
$title1, // title
$legend1, // legend
$plotarea1, // plotArea
true, // plotVisibleOnly
0, // displayBlanksAs <--------
NULL, // xAxisLabel
NULL // yAxisLabel
I want it to display nothing if the value is 0, I tried Null and '', but that didn't seem to do anything.
2) Is there a way to center the data labels on the bars? I've got:
$layout2 = new \PHPExcel_Chart_Layout();
// Set the series in the plot area
$plotarea1 = new PHPExcel_Chart_PlotArea($layout2, array($series1, $series2));
And the values show up as intended, only at the top right, which is muddled because there's a line chart on top of a bar chart and the numbers are on top of each other. Is there a way to tell it to put the labels at "center"?
