Jasper Report 预览中元素的奇怪定位
Weird positioning of elements inside a Jasper Report preview
我正在使用 TIBCO Jaspersoft® Studio 6.8.0，但我在定位时遇到了一些问题。我认为定位会有点自动跟随 GUI，但显然它不是那样工作的。
我有一个子报表（现在不需要主报表）调用其他 2 个子报表，一个用于饼图，一个用于交叉表。他们都使用来自外部 json（本地 json）的子数据集工作得很好。
问题是我无法正确定位它们：我需要将饼图定位在页面的顶部，交叉表紧靠下方。
这是子报表（现在用作主报表）。你可以看到我正在使用模拟（xml 调用 json），我将在问题末尾添加 json。

我认为问题不会出现在子报表中...至少不会出现在操作部分，但我仍然不知道为什么会这样显示（3 页而不是 2 页和奇怪的定位)...它们是按顺序排列的，第一页、第二页和第三页
有什么建议吗？
您在饼图子报表中使用的解决方法导致生成的报表中出现空白 space。
您为饼图元素设置了 print when 表达式。这使得饼图不会为第二条和第三条记录打印，但即使图表不打印，详细信息带本身仍会占用其声明的高度。
解决此问题的一个简单方法是为带而不是图表元素设置 print when 表达式。这将使整个乐队不打印第二和第三张唱片。
但更正常的解决方案是将图表元素放在摘要带中（表达式时不打印），并完全删除详细信息带。
我正在使用 TIBCO Jaspersoft® Studio 6.8.0，但我在定位时遇到了一些问题。我认为定位会有点自动跟随 GUI，但显然它不是那样工作的。
我有一个子报表（现在不需要主报表）调用其他 2 个子报表，一个用于饼图，一个用于交叉表。他们都使用来自外部 json（本地 json）的子数据集工作得很好。

我认为问题不会出现在子报表中...至少不会出现在操作部分，但我仍然不知道为什么会这样显示（3 页而不是 2 页和奇怪的定位)...它们是按顺序排列的，第一页、第二页和第三页
有什么建议吗？
您在饼图子报表中使用的解决方法导致生成的报表中出现空白 space。
您为饼图元素设置了 print when 表达式。这使得饼图不会为第二条和第三条记录打印，但即使图表不打印，详细信息带本身仍会占用其声明的高度。
解决此问题的一个简单方法是为带而不是图表元素设置 print when 表达式。这将使整个乐队不打印第二和第三张唱片。
但更正常的解决方案是将图表元素放在摘要带中（表达式时不打印），并完全删除详细信息带。
