如何在碧玉報告中生成分頁條形圖

Question

我想要的是，某條記錄的第一頁的條形圖，然後是下一頁的記錄數等等。 我爲此搜索了很多，但沒有找到確切的解決方案。 Jasper報告甚至有可能嗎？

Answer 1

您可以使用報告組來完成此操作。

在iReport中打開您的報告。

1:-Open report and in Report inspector right click and select "Add Report Group" 

2:-Give any name (eg. splitter) and 
    select "Group by the following expression" and enter 
      $V{REPORT_COUNT} - 1 - (($V{REPORT_COUNT} - 1) % 3). 
    (here 3 means 3 bars in a page) 

Click next and select Add the group footer. 

3:- Open palette and drag and drop a chart element from the Palette into 
    the report designer on the group footer band. 

4:- Select Bar Chart, follow the wizard: 
    a:- "Reset type" = Group 

    b:- "Reset group" = splitter 
       (same name what you gave at the time of Report data set creation) 

    c:- add series in Details tab.
