问题 I have a chart report displaying indicator values over time. This indicator is a report parameter and can represent either a percent (%) or a currency ($) value.

问题 So I need a few simple pointers with the BIRT chart API. I am trying to draw a simple line chart of a numeric value over time. I have a vector of (Date,Double) pairs as input. I have read through the examples in org.eclipse.birt.chart.examples but not yet gained enough traction with the API to start making use of it. Just composing a org.eclipse.birt.chart.model.impl.ChartWithAxesImpl has me stumped. The eventual destination is an Eclipse editor, and that I can do. Is there a tutorial or book

问题 I have a Data Source, a Data Set and a Data Cube. The data cube has a group and a summary field with a count function. In the report I have a table sorted by that summary field. This table has a lot of rows (~1000) but I only want to show the first 5.

In your case this is a cross-table based on a datacube: Select the cross-tab -> filter tab -> Add

问题 I'm facing an issue with BIRT report generator. I created a report using the designer and having set its masterpage orientation to landscape and page type to A4, there's no way to get it working using the report engine of my server (it always renders with the portrait orientation). If I ommit pdfOptions adding, the problem still appears. However, it works when I use designer's preview option. That's my ReportRenderer class: import javax.servlet.ServletContext; import org.apache.commons

问题 We have BIRT 4.4.0 report with a report parameter of decimal data type. The report parameter gets rounded up/down to the nearest 10 in Data Set Preview Results (and when the report is run, but we've narrowed the problem to the Data Set).
