Curve Fitting: Origin 8: Introduction to Curve Fitting

Learn how to fit with a built-in fitting function and change the settings for the output curve to add more points. Also, learn how to define and fit with a user-defined function.

Thank you for this great explanation !

[vinony]

good and nice tutuorial for beginners..

Still a great tutorial even 10 years later using dinosaur windows XP

I need to fit the data points with function, " log(y/C)=Exp[A(x-B)] " where x axis is plotted in normal scale and y axis is plotted in log base 10 scale. How should I write the equation now?

[renatoberaldo]

how do I change the range of data ? .. I do not wanna check the total chart, only few points

How do we narrow fitting to only a specific amount of X-axis data?

I want to know how to draw the multiple curves without sine function

[JagdeepMohanta]

I have used this equation
y = A*x^(-0.5)*exp[-B/(x-x0)]
while compiling it shows compile failed and the reason is exp not declared

What is the solution please reply fast

Hello everyone
I saw video, but i want to draw a trendline from three point which not line. Can you show me the way for draw?

[hadjimed]

plz i have a graph with many curve and i went ton fit al of theme, how ?

[Femtophysiker]

Is there any tutorial for an advance 3d matrix plots?

[tuntunii]

parameter initialization is not showing any parameter say, y0, a, b..why? I have already complied the equation

[Femtophysiker]

Very basic! but excellent..I like origin
