JasperReports的iReport - 产生了一个总计 [英] JasperReports' iReport - generating a grand total
问题描述
我在组页脚区域中设置了一个变量数据类型,它为报表中的每个组中的计数生成小计。效果很好。
我想在报告的最后一页生成一个总计,简单地总结小计值。这很难弄明白。
有什么建议吗?
I have a variable datatype set up in the group footer band that generates a subtotal for the counts in each group in my report. Works great. I would like a grand total to generate on the last page of my report, simply summing up the subtotal values. This has been harder to figure out. Any suggestions?
推荐答案
您可以使用两个不同的 resetType
- 用于计算组中的总和(使用 resetType =GroupresetGroup =groupNamecalculation =Sum
properties)和计算整个报告的总和(使用 resetType =报告计算=总和
属性)。
You can use two variables with different resetType
- for calculating sum in group (with resetType="Group" resetGroup="groupName" calculation="Sum"
properties) and for calculating total sum for whole report (with resetType="Report" calculation="Sum"
properties).
