Steps to reproduce

1) Create a survey with at least a "Short Free Text" question type;
2) Enable on "Location" section map service OpenStreetMap or Google Maps (i haven't used Maps because i can't get an API key);
3) Enable on "Stats" section "Display map" and "Display chart";
4) Save, close, activate survey and do it;
5) With at least 1 response in that survey, come back to survey settings and go on "Statistics";
6) On "Output options" section, enable "Show graphs", then select PDF "Output format", then select all questions in "Response filters" and, in the end, click "Export images".

Expected result

I was expecting a PDF with a map with pins.

Actual result

I saw only data tables and graphs.
