Create Polynomial Curve Fit from IronPython

[Riley ODonnell]

I would like to add a polynomial curve to my visualisation with degree 4, a custom name, and set to update manually. I would then like to retrieve the parameters for the fitted model. The use case is fitting a model over multiple different time periods which can then be used in comparison calculations.

I currently have the following script which is just able to add the polynomial fit of specified degree:

from Spotfire.Dxp.Application.Visuals import ScatterPlot

from Spotfire.Dxp.Application.Visuals.FittingModels import PolynomialFittingModel

for viz in Document.Pages[1].Visuals:

if viz.Title == "title:

vis1 = viz.As[scatterPlot]()

fm = vis2.FittingModels

fm.Clear()

fm.AddNew(PolynomialFittingModel).Degree = 4
