Thank you David. I have come across something else about ViewPoint3D objects: where is the best place to set/get them in the Orson Charts heirarchy? In the application I am developing, I create the Chart3D object from the Chart3DFactory.createScatterChart() method (love these utility methods), then ...

First of all, thank you for Orson Charts! This software has been fun to learn and implement in a program for displaying inspection data. Constructor: ViewPoint3D(double theta, double phi, double rho, double orientation) If I understand the ViewPoint3D javadocs correctly, the theta, phi, and orientat...

John: Thanks for the ProbabilityAxis - I have downloaded it and been using it for some plot testing. I would suggest however that you change the name to NormalProbabiltyAxis as it is based on the normal distribution. I suggest this as I am thinking of developing a WeibullProbabilityAxis class, unles...

First of all, I have really enjoyed JFreeChart for the past seven years in conjunction with WebObjects development. It worked seamlessly. However, I recently started a standalone application using JFreeChart. I have 1 dataset in an XYPlot with the primary domain axis on the bottom, the primary range...

The problem with JFreeChart 1.0.9 is likely to be a bug that affects the output of JPEG files. It is fixed for the upcoming 1.0.10 release. I suggest you try writing your charts as PNG files, or downgrade to 1.0.8, or wait for the 1.0.10 release (already overdue). Ahh... switching to PNG works in 1...

Hmm... I will be the first to admit I am slow to upgrade JARs in my project. I have been using jfreechart-1.0.0-rc1.jar and jcommon-1.0.0-rc1.jar for about a year successfully generating scatterplots with background images and then exporting as JPEGs. The code is simple and uses a background image t...

Thanks for the help. The starting angle is hard-coded in the translateValueThetaRadiusToJava2D() method in the PolarPlot class. It's probably pretty straightforward to make it a user-configurable setting, but I didn't look closely to see if there is anything else that needs updating. I am looking in...

I have been using JFreeChart and webobjects now for a couple of years, producing some nice bar charts. They make a good combination, and for those of you wondering, buying the manual is very much worth it. But, I need to add polar plots now and I need to change the way JFreeChart renders the polar p...
