Graph issues, best fit calibration, numerical solution, convergence

Posted 4 years ago

Hi, I have a problem with the following graphic.

enter image description here

As you can see, the dark line has some issues with values between 0.04 and 0.05. the line comes from the best fit calibration where 3 equations are solved for 3 unknowns numerically. So, my guess is that there is a convergence problem in that interval.

Does anyone know how I can get rid, graphically of that erratic behavior? I know the problem is numerically and it does not affect the results much. however, if I can make the line look better without that multiple values at the middle it would be nice.

I am adding the code in case it may help.

Thanks, a.
