      Description

      When attempting to view the All logs report under Course -> Participants -> (chosen participant) -> Activity reports -> All logs, the chart image is broken.

      This appears to be started in the call to get_logs_usercourse() at line 114 in /course/report/log/graph.php.

      Replication instructions:

      1. Log in as an administrator or teacher
      2. Go to a course that has students enrolled
      3. Go to the participants page and pick one user
      4. In the navigation block, select the All logs activity report (Course -> Participants -> (picked user) -> Activity Reports -> All logs

      The chart image appears broken (or hidden because it is broken). Viewing just the image displays the error which occurs when the image is being produced.
