10. category area charts look like mountains, not horizons    jfree.org

Hi, I'm working on a project that includes some fairly simple area and line charts, and selected JFreeChart + Cewolf because of the low barrier to entry and robust configurability.

12. set size of chart data area.    jfree.org

This something that JFreeChart makes difficult unfortunately, because the data area is calculated as the space remaining after the titles, legend and axes have been laid out. You can sometimes fudge the correct result using the setFixedDimension() method in the Axis class, but that means you have to calculate the widest/tallest axis yourself, which is not a very clean solution.

13. put grid lines over area chart    jfree.org

There's no option to control this via the API, although it would make a nice addition. For now, the only workaround is to modify the draw() method in the XYPlot class (either directly or by copying the method into a subclass and modifying it there). The gridlines are drawn by method calls, so you just need to move those to a ...

33. Gradient Filled Area Charts with Outline    jfree.org

No, although it would be a nice feature. The difficulty is in doing the transformation of the gradient paint's anchor points - with a bar it is easy, just use the top and bottom of the bar.

53. Not all points are plotted in Stacked Area Chart???    jfree.org

Sorry, when making the example I found that my data points were the cause: these contain multiple y-values at the same x-value (for each series).
