The best way to ensure the bounds of the plot cover the range of data without inventing additional code is to avoid using setLowerBound / setUpperBound.

BoxAndWhiskerRenderer that acts the same for horiz and vert

I've taken the v1.0.10 BoxAndWhiskerRenderer class and made it work the same for both horizontal and vertical orientations (the default renderer acts differently for the two orientations).

Fredrik, Check out the API for legendTitle. http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/title/LegendTitle.html Depending on how you are making your plot the implementation would change. Say, if you were using one of the factories you would just set legend = false in the constructor, ...

Looks like the most straight forward way is to create your own legend http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/title/LegendTitle.html Check out one of Dave's examples to see it in use http://www.jroller.com/dgilbert/entry/ouch Look for this (I assume you want something different) ...

What's the difference between a heat map and a contour plot? They both deal with a gradient in three dimensions.

Um, try and enter log(0) in your calculator. It can't do it either.


Try putting a positive number in there and it should work.

First do the work to put one plot on a page. To do that you can either find some examples here in the forum or better yet, purchase the manual which will let you cut/paste. When you get that accomplished try adding your second plot (there isn't anything special to add another once you get one). Then...
