This is for a Physics research data analysis. So basically:
I have some data points I want to curve fit in LabOrigin.
Fitting all the points gives not so great values. so we tried fitting all the points before 200k which gave us better output values.
To show that the fitting isn't great for temperatures above 200k, my research advisor wants me to include all the data points in the graph, but mask all data points above 200k. That is, graph all data points, fit for points below 200k, mask those above 200k, but still have points showing in graph (even masked ones)
I found few solutions online but none of them that I tried give me the results we are trying to get. This may be because none of the points are outliers (outside the fitting line). I attached a picture below for what the graph should look after the fitting.
Does anyone know of any solutions I could try that would make the graph look like the picture in LabOrigin? I have not being having any luck finding anything online/research papers.
Thank you in advance. |

@NicholasSupport. I have already tried the solution you mentioned. The problem is when I click recalculate, it automatically removes the masked data points from the graph and instead looks like this. Which is not what we are going for.

Hello Salima,
I apologize for the delayed reply. I missed your response. I hope it is not too late for input!
It looks like you are looking at the Fitted Curves Plot in FitLinearN worksheet? Since masked data gets excluded from analyses, the Fitted Curves Plot in FitLinearN worksheet will never include any masked data points.
To achieve your desired effect, you must first plot the data, mask the data, then fit the data.

including masked points in a graph?
