I switched from gnuplot to Open Flash Chart 2 for drawing rating and distribution charts.

I kept the charts clean. I have green/yellow/red points according to the rating colours. I have tooltips for every rating point and the peak point is marked with a "Max" label.

These charts are integrated using 2 macros. I haven't implemented zooming or resizing, I think it looks good enough as they are now. For the correct user profile, I have the following page saved as template/userrating on wiki:

===================================================================================

h2. Rating %user%

==RatingChart(user="%user%")==

h3. Concursuri cu rating la care a participat

==Rounds(user="%user%" only_rated="1")==

==DistributionChart(user="%user%")==

*{"Ce inseamna si cum se calculeaza rating-ul?":documentatie/rating}*

===================================================================================

This huge diff is because I added a PHP library provided by Open Flash Chart to generate content for charts. For testing, you need the file www/static/swf/open-flash-chart.swf (not included in this diff). You can download it from http://teethgrinder.co.uk/open-flash-chart-2/downloads.php (version 2 Hyperion).

Known issue: When I right click on a chart, I can't save the image locally. I don't know why.
