Change y axis length without changing axis range
显示 更早的评论
Hi
I have the following code
mid_bin = [196.2500 268.7500 341.2500 413.7500];
corr_perct = [0.4167 0.9412 1.0000 0.8750];
f = fit(mid_bin', corr_perct', 'poly2')
plot(f,mid_bin',corr_perct')
axis([160 450 0 1])
As you can see, the fitted curve does not fit into the plot. Now I do NOT want to change the y axis range since with the upper limit 1 = 100% since my y-values can not have a value bigger than 1 (bigger than 100%) - but I want the fitted curve to be fully visible. How do I achieve that? Thanks

You may require an higher order polynomial to do that. You may require more data points to exaclty fit a curbve to the data

Your fit function generates y values greater than 1(see attached fig). This is becasue of the tolerances of the fit function. If you strictly want the data to be in the range, consider changing the fit function.

Increase the data points and use higher order polynomial function say poly6 or so. Otherwise incerase your y axis to 1.2 or so..

you can alos use fourier2 as a curve fitiign function
