[birt-charting-dev] can't display chart
|
Hi,
I want to display a birt design with the Eclipse-birt preview option.
My design (.rptdesign) has a table and a bar chart.
The problem is when I display the design, because I ONLY see the table.
Why can't I see the bar chart????
I think it's a configuration problem... but really, I've not idea.
Which *.jar there be at the classpath?
Can anybody help me, PLEASE????
Here is my class:
