我正在利用“iReports”编写“MySQL”数据来源的报告。 我试图利用报告小组组织这些信息。 此外,我有一张图表,显示目前分类的动向,显示每个页的脚本。 图表的重新编号为组,并放在栏目中以达到这一目的。 此外,当报告小组变更时,还强迫新页。
The problem that I am having is that when the Report Group changes, (at the last page of each grouping) I am left with an empty chart on that page. On the proceeding pages, the chart resumes with valid data.
没有人会问我如何解决这一问题?
- A good solution would have the chart displaying the data for the group.
- An okay solution would have the chart hidden at the time of a report grouping change
