How To Change Calculate Totals Using Iron Python

I have a Cross Table in my Spotfire Dashboard and am trying to change the "Calculate Totals" option using an Iron Python script.

I've found this link on Spotfire API. So, from what I understood, this information is stored in myVis.Totals. But, for whatever the reason, this seems to be a read-only property as can be seen here.

Have any of you ever had this problem and would know how to fix it?

This is my code:

from Spotfire.Dxp.Application.Visuals import *

# myVis is a script parameter of the type "Visualisation"
myVis = myVis.As[Visualization]()
myVis.Totals = CrossTableTotals.CalculationMode.SumOfCellValues

 

This is the error I'm getting:

Traceback (most recent call last):
  File "<string>", line 5, in <module>
AttributeError: can't assign to read-only property Totals of type 'CrossTablePlot'


System.MissingMemberException: can't assign to read-only property Totals of type 'CrossTablePlot'
