Notice that the color assignment changes. Excel Scatter-plots. A simple linear regression model includes only one predictor variable. To create a scatterplot with regression fit lines and groups, complete the steps for the option that best describes your data. This line can be calculated through a process called linear regression. Line and Scatter in MATLAB ® How to make a Line and Scatter graphs in MATLAB ®. I first plotted my data points then used the polyfit function to add a first-order line to my plot. Adding regression line to scatter plot can help reveal the relationship or association between the two numerical variables in the scatter plot. The line formed is called a line of best fit by eye.
