      0. You need a quiz in separate or visible groups mode, with some attempts.

      1. Go to Quiz -> Results -> Grades in the navigation. Make sure the graph at the bottom of the page appears.

      2. Select a group, and make sure there are now two graphs.

      3. Go to Quiz -> Results -> Statistics. Make sure there is a graph at the bottom of the page.

      4. If you can be bothered, disable the GD PHP extension, and make sure the graphs are replaced by a nice message saying that GD is required (rather than just being broken images).

      Description

      On the quiz results page (/mod/quiz/report.php?id=60&mode=overview) I am seeing a broken image. The image URL is /mod/quiz/report/overview/overviewgraph.php?id=3 When I access that URL directly I get the error "Fatal error: Call to undefined function ImageCreate() in /home/andrew/Desktop/code/moodle/int/master/lib/graphlib.php on line 1420"

      The error is expected as I do not the the GD PHP extension installed. Its not installed by default on Ubuntu. However it would be nice if we could avoid displaying a broken image if its not installed on the server.
