Get fit values from logistic curve (e.g. logged EC50) into calculated column

Hello Spotfire community,

I am working on a very large data set that basically consists of dose response curves - I have created a visualization that has a concentration value on the x axis and a reponse value on the y axis. My data is heavily trellised to show different conditions & I am using a logisitic fit model (add line - logisitic fit - one per color) to show curves for relevant data sets.

This works beautifully, but how to I get the fit values of the individual curves (e.g. Min, Max, EC50) into calculated columns to further work on them? I know I can export individual cuves, but I have thousands and just want to pull out the relevant fit parameters for each curve based on the subsetting of my data!

Thank you!
