我知道这里已有类似的帖子,但这对我不起作用。
背景: Jaspersoft Studio 6
我有这样的数据集:
在此数据集上创建了这样的交叉表:
如何将列组分类为prod c,prod a,prod b而不是current?
我尝试将此表达式按列组的表达式排序。
$F{product}.equals("prod c")? 1 : $F{product}.equals("prod a")? 2:3
但它说
编辑:添加源代码,这是没有排序的版本,它运行正常,没有错误但当然没有排序。

答案 0 :(得分:3)
如上所述@ tobi6,你可以在 orderByExpression 中使用 Measures (你可以另外使用带有$ V {}表达式的 Buckets 但是这可能是一个艰难的方式)
在您的情况下,最简单的方法是使用排序规则添加新的度量。
<measure name="productForSort" class="java.lang.Integer">
<measureExpression><![CDATA[$F{product}.equals("prod b") ? 1 : $F{product}.equals("prod c") ? 2 : 3]]></measureExpression>
</measure>
之后,您可以在 orderByExpression 表达式中使用此 Measure :
<bucket class="java.lang.String">
<bucketExpression><![CDATA[$F{product}]]></bucketExpression>
<orderByExpression><![CDATA[$V{productForSort}]]></orderByExpression>
</bucket>
对于我的测试 csv 数据源:
sales channel, product, amount
channel a, prod c, 5
channel a, prod a, 1
channel b, prod a, 3
channel a, prod b, 1
channel b, prod b, 1
结果是这样的:
当你看到&#34;产品b&#34; 首先出现时。
备注:
问题类似(重复)一篇非常棒的帖子Jasper Reports crosstab sorting with comparatorExpression。您可以在这篇文章中找到更多信息。
我的回答与@PetterFriberg的solution相似。但在这种情况下,我们可以省略 Comparator
的使用另外两个答案也很好,特别是@AndreasDietrich的R&amp; D
答案 1 :(得分:1)
使用按表达式排序时,无法访问字段 $F{}
,只能访问度量变量(来自{{3 }}):
表达式在交叉表组的上下文中进行评估,并且可以引用度量变量,这些变量将评估为总计。
修改强>
测量变量是在创建交叉表时预定义的。它们遵循一种模式(来自here,&#34;了解交叉表总变量&#34;):
如果有多个行或列组,则可以使用交叉表总变量来组合不同聚合级别的数据(例如,计算百分比)。可以使用以下内置变量:
•
<Measure>_<Column Group>_ALL
:指定列组和当前行中所有条目的总和。•
<Measure>_<Row Group>_ALL
:指定行组和当前列中所有条目的总和。•
<Measure>_<Row Group>_<Column Group>_ALL
:指定行和列组中所有条目的总和。您还可以从表达式编辑器中为“度量”的“属性”视图的“文本字段”选项卡上的“表达式”字段选择这些变量。
据我了解,您可以使用这些变量对结果进行分组和排序。这些变量显示在交叉表的表达式编辑器中(源代码中有截图)。
答案 2 :(得分:0)
仅供参考,对于我来说,我无法(在Jasper Studio 6.4中)从Order By下拉列表中选择GUI中的Measures,但是当我在GUI表达式框中手动输入或直接输入时,它会有效。进入xml。
创建变量以计算条件排序
<variable name="Data_Sort" class="java.lang.Double">
<variableExpression><![CDATA[($P{Variance}=="Positive" ? $V{Vol_Diff}:(($P{Variance}=="Negative") ? $V{Vol_DiffInverse} :$V{Vol_AbsDiff}))]]>
</variableExpression>
</variable>
在交叉表中创建一个度量来访问排序变量
<measure name="DataSort_Measure" class="java.lang.Double">
<measureExpression><![CDATA[$V{Data_Sort}]]></measureExpression>
</measure>
在我的rowgroup
的bucket的orderby表达式中使用Measure变量<rowGroup name="Well.WellName" width="150">
<bucket order="Descending" class="java.lang.String">
<bucketExpression><![CDATA[$F{Well.WellName}]]></bucketExpression>
<orderByExpression><![CDATA[$V{DataSort_Measure}]]>
</orderByExpression>
</bucket>
