OriginPro - adding theoretical functions on the measured points

In summary, to add theoretical functions on your measured points in OriginPro, use the "Add Function" feature. You can add multiple functions by clicking the "Add Another" button. To edit function parameters, double-click on the function line or right-click and select "Edit Function". It is possible to fit a function to your data using the "Fit Function" feature. Functions can be saved for future use in the User Function Library.

So I have a problem. I have a measurement of several different points and I would like to compare that to the theoretical function.

I'm not expert in origin. I've tried with simulated curve, but I cannot get the points and curve on the same graph :\

How can I do that?

Thanks...

FAQ: OriginPro - adding theoretical functions on the measured points

How do I add theoretical functions on my measured points in OriginPro?

To add theoretical functions on your measured points in OriginPro, you can use the "Add Function" feature. Simply click on the "Add Function" button on the toolbar or go to the "Analysis" menu and select "Add Function". This will open a window where you can select the type of function you want to add and customize its parameters.

Can I add multiple theoretical functions on my measured points in OriginPro?

Yes, you can add multiple theoretical functions on your measured points in OriginPro. After adding the first function, you can use the "Add Another" button in the "Add Function" window to add another function. You can repeat this process to add as many functions as you need.

How do I edit the parameters of a theoretical function in OriginPro?

To edit the parameters of a theoretical function in OriginPro, double-click on the function line in the graph or right-click on it and select "Edit Function". This will open the "Edit Function" window where you can change the parameters and see the changes reflected in the graph in real-time.

Is it possible to fit a theoretical function to my measured data in OriginPro?

Yes, OriginPro offers the option to fit a theoretical function to your measured data. You can use the "Fit Function" feature, which can be accessed by clicking on the "Fit" button on the toolbar or going to the "Analysis" menu and selecting "Fit Function". This will open a window where you can select the function and customize its parameters to fit your data.

Can I save my added theoretical functions in OriginPro for future use?

Yes, you can save your added theoretical functions in OriginPro for future use. Simply click on the function line in the graph, go to the "Format" menu, and select "Save as User Function". This will save the function in your User Function Library, which can be accessed anytime from the "User-defined" tab in the "Add Function" window.
