I´m testing the 33chartcreate-column.php example from PHPExcel library example.The code is:

What I want:
Is there any way to rotate the labels like in the second picture?(I mean before generating the .xslx file,via code in the php file that allows the previous code). I´m using PHPEXCEL version 1.8.0

Answer
I have discovered that the PHPExcel library,automatically rotate the labels.It depends on the width of the chart,if you reduce the width of the chart.The labels apear like in the second picture.By code I don´t know how to do that,but as I say,if you reduce the chart width the labels looks like in the second picture. And also depends on the length of each label.
