Hi all,
I'm trying to create a chart programmatically, and like test I've copied
a method in org.eclipse.birt.chart.examples_2.1.1.v20070705-1847. My
Datasets are this:
TextDataSet categoryValues = TextDataSetImpl.create( new String[]{
"March", "April", "May", "June", "July"} );
NumberDataSet orthoValues1 = NumberDataSetImpl.create( new double[]{
12.5, 19.6, 18.3, 13.2, 26.5
} );
When Birt executes my class it always throws this exception:
java.lang.NullPointerException, at
org.eclipse.birt.chart.factory.Generator.getRowExpressions
Any idea ?
Thanks,
Salvatore
p.s: I am depressed for all these problems to create a very stupid and
trivial chart.
