The first image is what i would like to achieve and the second and third images are my values and the first attempt at the plot.
I would like to plot the trust region at every iteration. i am doing a nonlinear least-squares fitting and using the gsl library.
I did some changes to one of the source codes of the gsl library called "trust.c" and printed out the trust radius at every iteration.
i don't think scaling it is a good idea or that it would achieve the desired result of picture number 1 since the values vary largely.
Is there anyway else i can plot it?
fit_attempt 1 and fit_attempt 2 are the fit parameters since the fit is 2 dimensional.
my values vary largely so i cannot properly see the trust region radius even when i zoom in since they are very close together . how can i fix this ?
