ich have a problem with a function i created a long time ago and now have to use again but i doesn't work as i used it the last time. The fit function uses interpolated data of rheology measurements and looks like this:
I have 7 interpolated curves that represent different p (pressure) values. The problem i have now is that this fit should calculate one (!) set of bm1, bm2, bm3 etc. for different values of p. I know that i had to activate or deactivate something so that origin does not calculate different sets for each p, but i tried out everything and still can't remember what i have to change. Hopefully someone here can help. If it's important, function type is set to Y-form (German Version).
Kind Regards, Tobias
