Heyhey,

I have a problem with the follwing lines

fit_func = fittype("poly1");
fitdata = fit(XValues,YValues,fit_func);
h=plot(ax,fitdata);

-> so I got the error

Error using plot
Data must be numeric, datetime, duration or an array convertible to double.

If I use this line instead:

h=plot(fitdata);

Everything is fine

So my question: how am I able to use plot to creates the line in the axes specified by ax?

@Alexander Richter - are you using the same code or something different? Please provide details.

@Alexander Richter No updates from my side. Still using it without the specification of ax

plot(fitdata, 'Parent', hAxes)

where hAxes is the handle to your axes.

Why is it possible to specify the parent axes (a Name Value pair) for sfit objects but not for cfit?

@Marleen - you may want to ask this as a new question.
