I am trying to "trellis" a summary table using a script. The TrellisVisualization is not available for the SummaryTable class. Using the GUI, I can trellis a summary table by assigning a specific column to the Categorization property under Columns Properties. However, while using the IronPython script, I don't see any property named Categorization for the SummaryTable object. So, I tried assigning the column to the CategoryAxis as follows:

    mySummaryTable.CategoryAxis = "<[myColumn]>"

But this throws an error:

    AttributeError: 'SummaryTable' object has no attribute 'CategoryAxis'

I also tried using Axis or CategoricalAxisBase etc. as properties, but these options did not work out. If anyone has more ideas on this, please let me know. Thanks. RD

这里的关键问题是 Summary Table 类下的 CategoryAxis 属性是 GroupByAxis 类的这个视觉对象的 GET。您可以通过使用 print 命令并获取有关对象的信息来看到这一点：

print mySummaryTable.CategoryAxis

结果是我的 Spotfire 示例：
<Spotfire.Dxp.Application.Visuals.GroupByAxis object at 0x000000000000002C [Spotfire.Dxp.Application.Visuals.GroupByAxis]>

不过，你实际上很接近。为了设置 CategoryAxis，您需要像这样设置 CategoryAxis 的 Expression 属性：

from Spotfire.Dxp.Application.Visuals import SummaryTable

mySummaryTable = myVisual.As[SummaryTable]()
mySummaryTable.CategoryAxis.Expression = "<[COLUMN]>"

如果您需要将实际列名传递给其中而不是硬编码，我将连接表达式语法并将表达式设置为等于该变量：

myColumnExp = "<[" + myColumnName + "]>"
mySummaryTable.CategoryAxis.Expression = myColumnExp

如果您需要对此进行任何澄清，请告诉我。我的 Spotfire 版本是 v6.5.2.26，我的 API 信息来自https://docs.tibco.com/pub/doc_remote/spotfire/6.5.0/api/Index.aspx
