[news.eclipse.birt] Chart Engine API problems creating Pie Chart

[nikolai.raitsev@xxxxxxxxx (Nikolai)]

Hello,

I have downloaded Webinar Chart Engine examples from Jason Weathersby 
(http://www.birt-exchange.com/devshare/designing-birt-reports/463-birt-chart-engine-api-webinar-examples/)

and I'm trying to run SerializerExample with Pie chart, but I get a 
ChartException:

org.eclipse.birt.chart.exception.ChartException: Category runtime series 
count (here 0) for a chart without axes must 1
	at 
org.eclipse.birt.chart.render.BaseRenderer.instances(BaseRenderer.java:2401)
	at org.eclipse.birt.chart.factory.Generator.build(Generator.java:1040)
	at SerializerExample.<init>(SerializerExample.java:395)
	at SerializerExample.main(SerializerExample.java:312)

what going wrong here?

Thanks for answering and best regards,

Nikolai
