JavaFX 2 XYCharts and Java 7 Features

All but one of these (the PieChart) are ‘2 axis charts’ (specific implementations of the XYChart). In this post, I look at the commonality between these specializations of XYChart.

groovy-logo

One of the many features that makes Groovy an attractive scripting language is its built-in command-line argument support via CliBuilder. I have written about CliBuilder before in the posts Customizing Groovy’s CliBuilder Usage Statements and Explicitly Specifying ‘args’ Property with Groovy CliBuilder.
