/**
* Chart themes give more control over chart output, including
* the creation of the JFreeChart object itself. Also, chart themes
* affect a whole range of chart types across multiple reports and are not necessarily tied to
* a specific chart element within a report. They can even apply globally to all charts within
* a given JasperReports deployment, applying a new look and feel to all charts created.
*
* A chart theme can be set globally using a configuration property within the
* jasperreports.properties
file as follows:
*
* net.sf.jasperreports.chart.theme=<theme_name>
*
* The global chart theme can be overridden at report level using the following report
* property in the report template:
*
* <property name="net.sf.jasperreports.chart.theme" value="<theme_name>"/>
*
* If needed, at chart element level, the chart theme is specified using the theme
attribute.
