Statistics and Response Browsing

• usejpgraph: ^{(Obsolete since 1.8)} The JPGraph-library lets you display the results of your survey in the statistics part of LimeSurvey  in bar- and pie charts. If you have a correctly configured jpgraph class set up on your server, you can turn this feature on or off (1=on, 0=off). Please have a look, every version of PHP needs another version of JPGraph! This feature is currently in development, so expect a few weird outcomes.
• jpgraphdir: ^{(Obsolete since 1.8)} The physical disk location of the jpgraph class scripts. This setting is only required if $usejpgraph is equal to 1.
• jpgraphfont: ^{(Obsolete since 1.8)} The font to use with graphs. A failsafe setting would be "FF_FONT1"
• embedded: ^{(Obsolete since 2.0)} If you want to integrate LimeSurvey into another page then you can turn off sending HTML headers by using this setting and point instead to the header method of a custom function. This is a dirty hack but should work for a quick integration.
• filterout_incomplete_answers: Control the default behaviour of  filtering incomplete answers when browsing or analyzing responses. For a discussion on incomplete Responses see Browsing survey results. Since these records can corrupt the statistics, an option is given to switch this filter on or off in several GUI forms. This parameter config.php is just the default state for the incomplete answer filter. The following options are available:
  • show: Show both complete and incomplete answers
  • filter: Show only complete answers
  • incomplete: Show only incomplete answers
• strip_query_from_referer_url: This setting determine if the referrer URL saves parameter or not. Default value is "false" (in this case referrer URL saves all parameter). Alternatively this value can be set to "true" and the parameter part of the referrer URL will be removed.
• showaggregateddata: ^{(New in 1.8 )} When activated there are additional values like arithmetic mean and standard deviation at statistics. Furthermore data is aggregated to get a faster overview e.g. results of scale 1+2 and 4+5 are added to have a general ranking like "good" (1/2), "average" (3) and "bad" (4/5). This only affects question types "A" (5 point array) and "5" (5 point choice).
• PDF Export Settings: ^{(New in 1.85 )} This feature activates PDF export for printable survey and Print Answers. The PDF export is totally experimental. The output is mostly ugly. At this point no support can be given - if you want to help to fix it please get in touch with us.
  • usepdfexport: Set 0 to disable; 1 to enable
  • pdfdefaultfont: Default font for the pdf Export
  • pdffontsize: Fontsize for normal text; Surveytitle is +4; grouptitle is +2
  • notsupportlanguages = array('zh-Hant-TW','zh-Hant-HK','zh-Hans','ja','th');
  • pdforientation: Set L for Landscape or P for portrait format
• $showsgqacode: ^{(New in 1.91 )} This setting is used at the printable survey feature and defaults to false. If you set showsgqacode = true; the IDs for each question - and answer if applicable - will be shown; these IDs match the column heading at the Lime_survey_12345 table which holds the answer data for a certain survey. These Ids can be used for a code book for manual database queries.
