I hope this is the right place to post this query...

On the introduction page of each quiz there is a bar graph (chart) entitled "Recent Registered Player Scores". I understand that it provides a distribution spread of how many players gained which score, but could someone explain any significance attached to the different colours of the bars?

Also, one of my quizzes has no graph despite having been online and played more times than some of my other quizzes. Is this a glitch? And if so, can it be fixed, please?

I notice that most quizzes have on their info page a bar graph of the number of players and their scores.

But some quizzes, and I don't mean new quizzes, don't seem to have this bar. Is there a minimum number of players or ratings needed to produce this?

(I ask because specifically one of my quizzes is missing it, and it is older than some others that do have a graph.)

Thanks!

P.S. Is there a name for this graph?

I gather nobody knows? Or does anyone even know what I'm talking about?

I know what you're talking about, but have no idea why it is there for some quizzes and not for others. I don't usually find it very informative, anyway, so just glance at it when it is there. It may be that there is a minimum number of plays required before the graph is generated (too little data makes ugly graphs), not just a time issue.

I wondered why the Bar Charts were missing too

Hmmm... this seems to be one of the Great Mysteries of Fun Trivia. Is there anyone who knows how or why the bar charts get created? Or why some quizzes are missing them?

Well, they get created based on the amount of correct answers in the quiz and demonstrate the general difficulty of the quiz. They're generated based on that info, but I couldn't tell you when or why some don't have them (though I suspect it would be something refreshed at a specific time each week/month to lessen strain on the system).

I personally don't pay attention to them; looking at the quiz difficulty gives me a pretty good idea of how hard the quiz is/the scores they're getting.
