Re: panning code example
Hi uvoigt, I just had a look at your patch. It seems to be straightforward and effective. I just wonder about the best way to make these additional functions accessible to the user.

I implemented tecnical tools, trendline, trendchannel, fibonacii fan lines, fibonacii retracement lines, Text with arrow, Speedlines, Pitchfork. This was done by creating classes that implement the XYAnnotation interface and then simply do the drawing using Java2D. Interactivity was achieved by dete...

This looks like it could be interesting. I was able to add contect sensitive menus to the domain axis, range axis and chart area but I did this by extending the chart info object. This was limiting because you could only have one range axis. I also implemented dragging within the axis to implement z...

Take a look at the demo in this post
http://www.jfree.org/phpBB2/viewtopic.php?t=24606
It demo's points 1 & 2.
For #3 you would just need to create 2 datasets that represent the count/day, count/year and call plot.setDataset() to change the data.
