This will be fixed in the next release. In the meantime you could edit the WEB-INF\jsp\showChart.jsp file and have the line that starts with <cewolf:colorpaint color= to have <cewolf:colorpaint color="${chart.chartOptions.backgroundColor}"/>.
This will not resolve the issue for pdf and png output. For that, you would need to modify the WEB-INF\classes\art\chart\Chart.java, modify the getFinalChart() method, replace setBackgroundPaint(Color.decode(backgroundColor));
with setBackgroundPaint(Color.decode(chartOptions.getBackgroundColor()));.
After that, save, recompile and then restart the application.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Doesn't seem to have any impact. Anyone else know how to change this background color?
