title: Create Excel chart programmatically in PHP
body: <p>Do you have any idea on how to create a chart in an Excel sheet programmatically from PHP ?</p>
  
  <p>I know you can invoke the Excel COM object, but the server is running on a Linux machine...</p>
  
  <p>I already use the excellent PHPExcel library but they do not offer the option to create charts.</p>
  
  <p>Thanks !</p>
