1. MeterPlot and negative Ranges    jfree.org

I don't believe MeterPlot is handling negative values correctly. With MeterAngle at the default 270, a range of new Range(-10,100) will extend beyond the 270 degrees. In addition, for a chart with a range of (-100,100) will not plot -20. A negative to negative (-100, -50) will not plot correctly either. Thanks

I am playing with the example code you posted a week ago or so, and I'm not having much luck just playing with the methods and properties and API documentation and trying to get the control I want over the look / feel.

7. MeterPlot and empty space    jfree.org

Not so much stretched as proportional to the ChartPanel size. If the size of the ChartPanel that contains the Meter is a square, maybe the Meter could fill up the space. I noticed that when the ChartPanel size is smaller (about 200x200 ) the Meter is more of an ellipse (more height than width) than a circle with quite a bit ...

15. Little problem on MeterPlot and ThermometerPlot    jfree.org

Hello, A little detail is bugging me in those charts. In the XYPlot (for example), if there is no data (so if the dataset is empty or null), the "No data message" is displayed. For the MeterPlot and ThermometerPlot, it isn't. I wanted to ask you, David, if it is possible for you to add this behavior in the next release ...
