I tried to build a report containing a line chart, following this example:

http://dynamicjasper.com/docs/current/xref-test/ar/com/fdvs/dj/test/domain/chart/builder/LineChartBuilderTest.html

But I got this error instead:

Category series name is null.
net.sf.jasperreports.engine.JRRuntimeException: Category series name is null.

I've been dealing with this for three days, but I haven't found any workaround anywhere...

My dependencies:

'net.sf.jasperreports:jasperreports:6.17.0'
'com.lowagie:itext:2.1.7.js8'
'ar.com.fdvs:DynamicJasper:5.3.2'
