[英]Spotfire IronPython script: get Cross Table data
如何將數據對象輸出為文本。
crossTable = markMe.As[CrossTablePlot]()
print crossTable.Data
返回:
位於0x000000000000002C的Spotfire.Dxp.Application.Visuals.VisualizationData對象[Spotfire.Dxp.Application.Visuals.VisualizationData]
我也嘗試過:
for text in crossTable.Data:
print text
返回錯誤:
Microsoft.Scripting.ArgumentTypeException:對類型的非序列進行迭代
如何獲得繪圖數據,以便最終標記其中的項目?
您的問題是您要從可視化中獲取數據表本身,這不是記錄的集合,而是包含行值集合的列的集合。
以下內容將帶您到達那里。 我使用了一個數據集,其中“ test1”列包含6行,其值包括1到6。
以下代碼的總體流程如下:
碼:
from Spotfire.Dxp.Application.Visuals import CrossTablePlot
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
from Spotfire.Dxp.Data import DataValueCursor
from Spotfire.Dxp.Data import DataSelection
##Get our Data Table from our graph. Data Tables hold marking relations.
##Visuals just point to a marking set you specify
##and interact with it in the UI based on their DataTable.
crossTable = markMe.As[CrossTablePlot]()
crossSource = crossTable.Data.DataTableReference
##Get a Row Count
rowCount = crossSource.RowCount
##Index Set of all our rows
allRows = IndexSet(rowCount,True)
##Empty Index Set to fill with our desired markings
rowsToMark = IndexSet(rowCount,False)
##Pick the column we're interested in examining for values.
##You can create multiple cursors to look at multiple columns.
##Specify the name of your column. Mine is called test1.
colCurs = DataValueCursor.CreateFormatted(crossSource.Columns["test1"])
##Optional: Loop through to determine average value
colTotal = 0
for row in crossSource.GetRows(allRows, colCurs):
colTotal += int(colCurs.CurrentValue)
colAvg = colTotal/rowCount
##loop through our rows and add what we want to our index.
for row in crossSource.GetRows(allRows, colCurs):
##Get the index of our current row in the loop
rowIndex = row.Index
##Compare values and if TRUE then we add this row to our index
##Instead of hard coding you can refer to a document property
##or any other source of data like the average of your column.
##Optional: Print our current value to debug
#if int(colCurs.CurrentValue) > (2.5):
if int(colCurs.CurrentValue) > colAvg:
print colCurs.CurrentValue + " was added to the index! =]"
rowsToMark.AddIndex(rowIndex)
else:
print colCurs.CurrentValue + " was not added to the index... =["
##Set our marking equal to our rowsToMark index
Document.ActiveMarkingSelectionReference.SetSelection(RowSelection(rowsToMark),crossSource)

bearonspotfire也是編寫腳本的好資源。 我接受了他所做的工作,並在您的應用程序上做了一些改動。 他使用下拉菜單標記項目。
編輯diablo8226的問題:
flux(OP)和我在相同的假設下運行,即markMe作為相關可視化的輸入參數包含在內。 您也可以通過單擊“腳本輸入”窗口下方的“添加...”按鈕來包括此內容。 您可以使用markMe或任何名稱。 只需確保選擇“可視化”作為“類型”,然后選擇您的可視化。
或者,您可以輸入數據表本身,並跳過獲取數據表源的我的代碼,或使用如下代碼明確調用該表:
coll = Application.GetService[DataManager]().Tables
crossSource = coll.Item["TABLE_NAME"]
