How do you find the difference between two graphs (one being an excel file )and another one being generated by a sensor (so matlab outputs data)? (assume they have the same amount of data points)

Hi Labs,
I understand that you would want to compare plots of a set of data stored in Excel and data stored in MATLAB from a sensor.
This can be achieved by first loading the Excel data set into MATLAB using “readtable” function, and then plotting both available data sets on graphs.
2. “plot” function creates a 2-D line plot of the data in Y versus the corresponding values in X. Documentation for “plot” function - https://in.mathworks.com/help/matlab/ref/plot.html?searchHighlight=plot&s_tid=srchtitle_support_results_1_plot
3. Following is the example of how to show difference between two plotted data in graph – https://in.mathworks.com/support/search.html/answers/622243-how-to-show-difference-between-two-plotted-data-in-graph.html?fq%5B%5D=asset_type_name:answer&fq%5B%5D=category:matlab/geographic-plots&page=1
Hope this Helps.
