TreeMap properties(Hierarchy, Size by) using ironpython script in spotfire

Question

如何在Spotfire中使用ironpython脚本更改TreeMap属性（层次结构，大小依据）。

Answer 1

I found the solution:

from Spotfire.Dxp.Application.Visuals import Treemap
treeChart = vis.As[Treemap]()
vis.Title="tree map title"
treeChart.Data.DataTableReference = "Your Expression"
treeChart.ColorAxis.Expression = "Your Expression"
