We are running Lime Survey, and it is working well, but one thing that is slightly out for us is the PDF generated when you 'Get statistics for these responses', choose PDF format and tick 'show graphs'. We end up with PDFs that are twice the size, in pages, that they need to be. The stats for a question appear on one page, then the pie chart appears on another. Unless you have dozens of answers per question, this leaves a lot of white space in this document. We can, obviously, export without the pie charts, but we think they definitely enhance the results.
I couldn't find anything about getting the output to format differently on here so wondered if there is any way to do this.
I have written a tutorial to reduce the size of the pdf report by placing graphs and tables for the same question on one page therefore cutting it down to half the pages. Have look. It is pretty easy but helps a lot:
