Getting registration method object from SimpleElastix to generate plots in real-time

[ApoorvaDA]

I was hoping to use the registration utilities and registration callbacks from SimpleITK as defined in https://github.com/InsightSoftwareConsortium/SimpleITK-Notebooks to plot the metric values and registration errors with the number of iterations. Our computational Pipeline already implements a SimpleElastix filter and a parameter vector consisting of a sequence of transformations and respective parameters. Even though I can see the metric values being displayed on the console/log I do not see a direct way to access those and generate plots as SimpleElastix executes. Please suggest me a convenient way to achieve this. Is there any way to get the SimpleITK image registration method for a given parameter map?
